Irish Gaelic and Scottish Gaelic are two closely related languages that grew from the same Old Irish root. Their names carry two old prefixes that still show up today: O, meaning descendant, and Mac, meaning son, each followed by a personal name.
The names came through with them. Some are ancient personal names carried by kings and saints; others began as surnames built on the Gaelic words for son and descendant, then crossed back over into first-name use.
Below are 99 Gaelic names for boys, each with its origin, meaning, and a plain-English pronunciation, so you can tell the authentically Gaelic picks from the ones that only look the part.

Ahern
- Origin: Irish Gaelic
- Meaning: Lord of horses
- Pronunciation: uh-HERN
- Variations: Aherne, Hearn, Hearne
Ahern started life as the surname O’ Eachthighearna, “descendant of Eachthighearna,” and the Aherns were a notable medieval family whose motto was “per ardua surgo,” or “I rise through difficulties.”
As a personal name it breaks down into the Irish “each,” meaning “horse,” and “tighearna,” meaning “lord.” That gives you a boy’s name that literally reads as lord of horses, which is a lot of weight for two syllables to carry.
It has never been common as a first name, so your son would almost certainly be the only Ahern in his class. Parents who like Aidan and Ronan but want something nobody else has picked should give it a look.
Ailean
- Origin: Scottish Gaelic
- Meaning: Rock
- Pronunciation: AL-an
- Variations: Alan, Allan, Allen
- Namesakes: Ailean Maclean, one of the last Viking pirates of Scotland
Ailean is the Scottish Gaelic form of the English boy’s names Alan and Allan, both derived from a Celtic word meaning “rock.”
The best story attached to it belongs to Ailean Maclean, one of the last Viking pirates of Scotland, remembered as Ailean Nan Sop, or “Allan o’ the Wisp.” Spelled the Gaelic way, the name looks far more distinctive than the flat, mid-century Alan most people picture. Say it out loud, though, and it stays easy for anyone to repeat.
Alasdair
- Origin: Scottish Gaelic
- Meaning: Defender of men
- Pronunciation: AL-iss-ter
- Variations: Alistair, Alister, Alasdhair
Alasdair is the Scottish Gaelic form of Alexander, and it keeps the same warrior-flavored meaning: defender of men.
The spelling is the whole point here. Alistair and Alister look tidy and English; Alasdair looks like it came off a Hebridean gravestone, which is exactly what parents chasing an authentic Scottish name are after. It also gives you the easiest nickname on this list, since Ally and Al both work without any explanation.
Alexander remains a fixture in Scotland while the Gaelic spelling stays rare, so Alasdair reads as a considered choice rather than a trend.
Alby
- Origin: Irish Gaelic
- Meaning: White
- Pronunciation: AL-bee
- Variations: Ailbe, Ailbhe, Albie
- Namesakes: Saint Ailbe of Emly, an early patron saint of Munster
Alby is a shortened form of the Irish Gaelic name Ailbe, and it is a name meaning “white.”
Its most famous bearer was Saint Ailbe, an early bishop long venerated in Munster. The modern short form has done far better in Ireland than the saintly original, while neither spelling has broken into the American charts. That makes Alby a genuinely unusual pick for an Irish American family, and one that still sounds friendly rather than fussy.
Aodhan
- Origin: Irish Gaelic
- Meaning: Little fiery one
- Pronunciation: AY-dawn
- Variations: Aedan, Aidan, Aiden
- Namesakes: Saint Aidan of Lindisfarne, the Irish missionary bishop who died in 651
Aodhan is a male name meaning “little fiery one.”
It is a pet form of Aodh, a name that meant “fiery” and belonged to a Celtic sun god before it belonged to several Irish kings. English speakers know its anglicized descendant far better: Aidan, along with Aiden and Ayden.
The Gaelic spelling asks a little more of everyone who reads it, and rewards you with a name that has real history behind it rather than a 2000s trend. Saint Aidan of Lindisfarne, the Irish missionary who carried Christianity into Northumbria, is the bearer most likely to come up if anyone asks.
Bain
- Origin: Scottish Gaelic
- Meaning: White or fair
- Pronunciation: BAYN
- Variations: Bayne
Bain comes from the Gaelic “ban,” meaning “white,” and in the Scottish Highlands it long served as a nickname for fair-haired men. One syllable, four letters, no ambiguity about how to say it. Nirvana fans have an obvious angle on it as a short form of Cobain, and anyone else simply gets a crisp, slightly severe name that pairs well with longer surnames.
Bairre
- Origin: Irish Gaelic
- Meaning: Fair-haired
- Pronunciation: BAR-ruh
- Variations: Barra, Barry, Finbar
- Namesakes: Saint Finbarr of Cork
Bairre is a pet form of the Gaelic name Finbar, and it means “fair-haired,” which makes it a natural fit for a blonde baby.
Its namesake is the legendary saint of Cork, credited with banishing a serpent from the city with holy water and, in one story, with keeping the sun in the sky for two weeks after his death. Barry is the anglicization everyone knows, and Barra is the form still used in Irish. Bairre sits between them, softer than Barry and easier on a form than Finbar.
Blaine
- Origin: Scottish and Irish Gaelic
- Meaning: Yellow
- Pronunciation: BLAYN
- Variations: Blain, Blane, Blayne
- Namesakes: Blaine Gabbert, NFL quarterback
Blaine is a Scottish and Irish surname taken from the Gaelic given name Blaan, meaning “yellow.”
Americans have used it as a boy’s name since the early 1900s, which gives it an unusual double life: old enough to feel settled, uncommon enough to feel fresh. It reached Ireland much later, arriving on the charts in the 1980s. Actor Blaine Maye and quarterback Blaine Gabbert are the bearers most likely to come to mind.
Blair
- Origin: Scottish Gaelic
- Meaning: Field or plain
- Pronunciation: BLAIR
- Variations: Blaire, Blare
Blair comes from the Scottish Gaelic “blar,” meaning “field, plain, or meadow,” and it began as a place name before anyone wore it.
Where you live decides how it reads. In Scotland and Canada it is still a boy’s name; in the United States it swung firmly to girls after Gossip Girl and a run of preppy sitcom characters. If you like the sound and are unbothered by that, Blair on a boy has a clipped, confident quality that few one-syllable names manage.
Brawley
- Origin: Irish and Scottish Gaelic
- Meaning: Descendant of Brolach, or excellent
- Pronunciation: BRAW-lee
- Variations: Brawly, Brolly
- Namesakes: Brawley Nolte, son of actor Nick Nolte
Brawley has two plausible roots, and both suit a loud toddler. It may come from the Gaelic surname O’Brolaigh, “descendant of Brolach,” or from the Scots word “brawlie,” meaning “excellent” or “good.”
Nobody used it as a first name until Nick Nolte chose it for his son in the 1980s. It has stayed rare ever since, so you get a name that sounds like a rowdy nickname but comes with genuine Gaelic footing.
Brendan
- Origin: Irish Gaelic
- Meaning: Prince
- Pronunciation: BREN-dan
- Variations: Brendon, Breandan, Brendain
- Namesakes: Saint Brendan the Navigator
Brendan means “prince” or “king,” by way of the Gaelic Breandan and the older Old Irish Brenainn, which trace back to a Welsh root, “breenhin.”
Its saint is the best travelled on this list. Brendan the Navigator supposedly sailed west with 16 monks looking for the Garden of Eden, a voyage retold for centuries and occasionally floated as a pre-Viking crossing of the Atlantic.
The name has the rare distinction of being widely recognized without being overused right now, and Brandon and Brendon give you nearby spellings if you want one.
Brogan
- Origin: Irish Gaelic
- Meaning: Descendant of Brogan, or little shoe
- Pronunciation: BROH-gan
- Variations: Brogain, Broghan
- Namesakes: Saint Brogan, scribe to Saint Patrick
Brogan works as both a surname, from O’Brogain, and a given name, and it shares a root with the brogue, the sturdy Irish shoe.
Saint Brogan, remembered as a scribe to Saint Patrick, is the reason it was ever used for boys in the first place. In Ireland it has become a genuinely fashionable choice rather than a heritage one. The built-in nickname is Bro, which will either delight you or decide the matter against it.
Caden
- Origin: Irish Gaelic
- Meaning: Battle
- Pronunciation: KAY-den
- Variations: Cadan, Caiden, Cayden, Kaden
Caden most likely traces to the Old Irish “cath,” from the Celtic “katus,” meaning “battle.”
This adorable “C” name rode the same wave as Aidan, Hayden, Braden, and Jaden, and it is one of the more used spellings of the bunch. That is worth knowing before you commit: Cade, Cadan, Caedan, Caiden, Cayden, Kadan, Kaden, and Kayden all exist, so your son will spend a fair amount of his life spelling it out.
Cailean
- Origin: Scottish Gaelic
- Meaning: Whelp or cub
- Pronunciation: KAH-lun
- Variations: Colin, Collin, Cullen
Cailean descends from the Old Irish name Cuilen, borne by a medieval Scottish king, and it means “whelp” or “cub.”
Its anglicized forms went in three directions: Colin, which now reads as thoroughly ordinary, Collin, which reads as its 1990s cousin, and Cullen, which will forever belong to a family of vampires. Cailean sidesteps all three while sounding almost identical, which is a neat trick for parents who like the sound but not the associations.
Cairbre
- Origin: Irish Gaelic
- Meaning: Charioteer
- Pronunciation: KAR-bruh
- Variations: Carbery, Carbry, Carbary
- Namesakes: Cairbre Cuanach, an Ulster warrior of Irish legend
Cairbre was a common name in medieval Ireland, built from “corb,” meaning “chariot,” and “ri,” meaning “king.”
It belonged to a crowd of mythological figures, including the Ulster warrior Cairbre Cuanach and Cairbre, son of the god Ogma. Today you are far more likely to meet its anglicizations, Carbery and Carbry, than the original. Give a boy the Gaelic spelling and you are handing him a name with chariots in it, which few three-syllable options can claim.
Callum
- Origin: Scottish Gaelic
- Meaning: Dove
- Pronunciation: KAL-um
- Variations: Calum, Colm, Column
Callum comes from the Latin name Columba, meaning “dove,” a bird early Christians linked with purity and peace.
That association is not incidental. Saint Columba carried Irish Christianity to Iona, and Gaelic families named sons for him for centuries afterward.
This old-fashioned name came roaring back in Scotland and Ireland, and it has climbed steadily in the United States since first entering the top 1000 in 2008. The single-l Calum is the older Scottish Gaelic spelling if you want to go one step closer to the source.
Carlin
- Origin: Irish Gaelic
- Meaning: Little champion
- Pronunciation: KAR-lin
- Variations: Carlan, Carlyn, Caireallan
- Namesakes: Carlin Isles, American rugby sevens player
Carlin is an anglicized form of the Irish surname O’ Caireallain, “descendant of Caireallan,” and it doubles as a pet form of the personal name Caireall, which carries the sense of a warrior or champion.
If Carl feels like a name that peaked decades ago, Carlin is the cool name hiding one syllable away from it. Literary critic Carlin Romano and rugby sevens speedster Carlin Isles are its best known modern bearers.
Carrig
- Origin: Irish Gaelic
- Meaning: Rock
- Pronunciation: KEHR-ig
- Variations: Carrick, Carraig
Carrig is a reduced form of De Carraig, meaning “rock,” and it points back to a rocky stretch of Irish countryside rather than to a person. It is widely thought to be where the far more familiar Craig came from. That makes Carrig a useful option if you want Craig’s solidity without its 1970s hangover. Carrick is the spelling you will see on maps.
Casey
- Origin: Irish Gaelic
- Meaning: Vigilant or watchful
- Pronunciation: KAY-see
- Variations: Kacey, Kacie
Casey comes from the Irish “cathasaigh,” meaning “vigilant” or “watchful.”
It was one of the defining unisex names of the 1980s and 90s in the United States and has cooled on both sides since, while holding on far better in Ireland. The spelling options are unusually forgiving, from Kacey to Kayce, and every one of them keeps the same easygoing sound.
Cathal
- Origin: Irish Gaelic
- Meaning: Battle ruler
- Pronunciation: KAH-hal
- Variations: Cahal, Cathel, Cahill, Kathel
- Namesakes: Cathal Brugha, the Irish revolutionary commemorated in Dublin street names
Cathal joins “cath,” meaning “battle,” to “val,” meaning “rule,” and it was especially common in medieval Munster and Connacht.
Note the pronunciation before you fall for the spelling: it is KAH-hal, with the t silent, which trips up almost every American who meets it in print first. The name was sometimes anglicized as Charles, though the two share nothing beyond a first letter.
Ireland still uses it heavily and the United States barely at all, so Cathal is about as far from a trending name as a genuinely popular name can get. Dublin has both a Cathal Brugha Street and a Cathal Brugha Barracks, named for the revolutionary who died in 1922.
Ciaran
- Origin: Irish and Scottish Gaelic
- Meaning: Little dark one
- Pronunciation: KEER-an
- Variations: Kieran, Keiran, Kiaran, Kyran
- Namesakes: Actor Ciaran Hinds
Ciaran is a boy’s name meaning “little dark one,” built from “ciar,” meaning “black” or “dark,” plus a diminutive ending.
The name runs deep in Irish history. Ciar, son of the mythological king Fergus mac Róich, gave his name to County Kerry, and two early saints called Ciaran were counted among the Twelve Apostles of Ireland.
Ireland uses it steadily while the United States mostly meets it through Kieran, so the Ciaran spelling stays a distinctive alternative to Connor, Collin, or Caden. Actor Ciaran Hinds keeps the original spelling in front of English-speaking audiences.
Cleary
- Origin: Irish Gaelic
- Meaning: Descendant of the cleric
- Pronunciation: KLEER-ee
- Variations: Clery, O’Cleary
Cleary comes from the Gaelic surname O’Clerigh and originally marked out the son or descendant of a scribe, clerk, or cleric. The O’Clerys were hereditary historians, which is a pleasing thing to have behind a name. It is often anglicized as Clark even though the two are unrelated, and it remains rare as a first name, so a boy named Cleary will not be sharing it.
Conall
- Origin: Irish Gaelic
- Meaning: Strong wolf
- Pronunciation: KON-al
- Variations: Conal, Connell, Conaill
- Namesakes: Conall Cernach, hero of the Ulster Cycle
Conall means “brave wolf,” from the Irish “con,” meaning “hound” or “wolf,” and “gal,” meaning “bravery” or “valor.”
In Irish myth, Conall Cernach helped the hero Fraech recover his abducted wife and later avenged the death of Cu Chulainn. That is a lot of legend attached to a name that stays easy to say and spell.
It has climbed steadily in Ireland since the 1960s, and this powerful name gives you Con and Coney as ready-made nicknames.
Connor
- Origin: Irish Gaelic
- Meaning: Lover of hounds
- Pronunciation: KON-ur
- Variations: Conor, Conner, Konnor
- Namesakes: Hockey player Connor McDavid and fighter Conor McGregor
Connor is the anglicized form of Conchobhar, the name of the semi-legendary king of Ulster who presides over most of the Ulster Cycle.
It has been an American top-100 fixture since 1992, which makes it the most familiar name on this list by a wide margin. In Ireland it peaked earlier and has been drifting down since. If you want the sound without the crowd, the single-n Conor is the Irish spelling, worn by UFC fighter Conor McGregor, while hockey star Connor McDavid keeps the double-n version in play.
Conroy
- Origin: Irish Gaelic
- Meaning: Hound of the plain
- Pronunciation: KON-roy
- Variations: Conry, O’Conroy
- Namesakes: Surrealist painter Conroy Maddox
Conroy is the anglicized form of O’Conraoi, meaning “hound of the plain.”
The Conroys were poets and historians to the Kings of Connacht across several centuries, which is an unusually literary pedigree for a name that sounds this rugged. Modern bearers include the English surrealist painter Conroy Maddox and architect Francis Conroy Sullivan, who trained under Frank Lloyd Wright. Roy makes an easy short form if the full name feels formal.
Cuchulain
- Origin: Irish Gaelic
- Meaning: Hound of Culann
- Pronunciation: koo-HULL-un
- Variations: Cuchulainn, Cu Chulainn, Chulainn
Cuchulain belongs to the greatest warrior in Irish mythology, the son of the god Lugh, who earned the name after killing the hound of the smith Culann and offering to guard the man’s house in its place.
He is said to have defended all of Ulster single-handedly at 17, and in battle he entered a warp spasm that left him unable to tell friend from foe, which is the closest thing early Irish literature has to the Hulk.
It can be said koo-HULL-un or koo-KULL-un depending on who taught you, and Chulainn is the shorter spelling. This is a heavy name to hand a small boy, but few carry more story.
Curran
- Origin: Irish Gaelic
- Meaning: Spear or dagger
- Pronunciation: KUR-an
- Variations: Curren, Currin, Corrin
Curran descends from three separate Irish families, O’Corrain, O’Cuirin, and Mac Corraidhin, and as a personal name it traces to the Gaelic “corradh,” meaning “spear.” The sound is friendlier than the meaning, which is part of its appeal. Cur and Ran are both usable short forms, and the second suits a boy who never stops moving.
Daithi
- Origin: Irish Gaelic
- Meaning: Swiftness or nimbleness
- Pronunciation: DAW-hee
- Variations: Dathi, Dahey, Dahy
- Namesakes: Daithi, the semi-historical fifth-century High King of Ireland
Daithi means “swiftness,” and it is pronounced DAW-hee, with the th disappearing entirely.
It was borne by a semi-historical fifth-century king of Ireland who reportedly sent Irish fleets to raid the Roman Empire. English speakers often anglicize it as David, though the two names have nothing in common beyond a rough resemblance on the page. Irish parents have taken to it again in recent decades, while it remains almost unknown in the United States.
Daley
- Origin: Irish Gaelic
- Meaning: Gathering or assembly
- Pronunciation: DAY-lee
- Variations: Daly, Dailey, Dawley
Daley comes from the surname O’Dalaigh, built on “dalach,” meaning “assembly” or “gathering place.” The O’Dalaighs were a famous bardic family, which gives the name a poetic streak it does not advertise. Mostly it still works as a surname, but as a short form it is a livelier alternative to Dale.
Dallas
- Origin: Scottish Gaelic
- Meaning: Meadow dwelling
- Pronunciation: DAL-us
- Variations: Dallis, Dalles
Say Dallas and most Americans picture Texas, cowboy boots, and a football team. The name is Scottish long before it is Texan, from the Gaelic “dail” and “fas,” meaning “meadow dwelling.”
There is an English strand too, from “dael,” meaning “valley,” and “hus,” meaning “house.” Either way you land on a name about open ground, which is a gentler idea than the skyline suggests. It is used for both boys and girls in the United States, so it sits comfortably in the unisex column.
Darragh
- Origin: Irish Gaelic
- Meaning: Oak tree
- Pronunciation: DAR-ah
- Variations: Dara, Daragh, Darach
Darragh comes from the Old Irish “daire,” meaning “oak tree,” which is why it is occasionally anglicized as Oakes.
It is one of the genuinely popular boys’ names in modern Ireland and almost unheard of outside it, an unusual combination that makes it feel both established and fresh depending on which side of the Atlantic you are standing on. Dara is the shorter Irish spelling and works for girls as well.
Darren
- Origin: Irish Gaelic
- Meaning: Uncertain, possibly great
- Pronunciation: DAR-en
- Variations: Daren, Darin, Darrin
- Namesakes: Director Darren Aronofsky and actor Darren Criss
Darren is an honest puzzle. Some trace it to Darragh, others to a Gaelic surname carrying the sense of “great,” and nobody has settled it.
What is certain is its arc. It was everywhere in the United States and England in the 1960s and 70s, then vanished from the nursery and moved into the workplace, while Ireland kept using it far longer. Director Darren Aronofsky and Glee actor Darren Criss are its most visible modern bearers. Names of this vintage tend to come back around, so an early adopter could look prescient.
Diarmuid
- Origin: Irish Gaelic
- Meaning: Without injunction
- Pronunciation: DEER-mid
- Variations: Diarmaid, Diarmait, Dermot, Dermod
- Namesakes: Diarmuid Ua Duibhne, the warrior who eloped with Grainne
Diarmuid probably breaks down into “di,” meaning “without,” plus a second element read as either “injunction” or “envy,” which is a subtler idea than the usual battle-and-wolves fare on this list.
Kings, saints, and heroes carried it. The most famous is Diarmuid Ua Duibhne, the warrior of the Fianna who ran off with Grainne on the eve of her wedding to Fionn mac Cumhaill and was hunted across Ireland for it.
In English it is often swapped for Jeremiah or Jeremy, and Dermot is the anglicization that actually stuck. The Scottish Gaelic form is Diarmad.
Donn
- Origin: Irish Gaelic
- Meaning: Brown or chief
- Pronunciation: DON
- Variations: Don
Donn works as a name in its own right and as a casual short form for Donal, Donald, or Donncha.
In Irish mythology Donn was the god of the dead, and in parts of Ireland he survived into folklore as a phantom horseman riding a white steed. That is a striking amount of atmosphere for four letters. Modern Donns get a name that reads as understated rather than austere.
Donncha
- Origin: Irish Gaelic
- Meaning: Brown-haired warrior
- Pronunciation: DUN-uh-kha
- Variations: Donnchadh, Donnacha, Donagh, Duncan
- Namesakes: Donncha mac Briain, son of High King Brian Boru
Donncha is a boy’s name meaning “brown-haired warrior.”
Irish and Scottish kings wore it for centuries. The best remembered is Donncha mac Briain, son of Brian Boru, the High King who broke Viking power in Ireland.
It fell silent for generations and picked up again in Ireland in the mid-2000s. It has never registered in the United States, where the opening syllable reads too close to Donna for most parents. Duncan is the anglicized descendant if you want the history in a form nobody will misread.
Douglas
- Origin: Scottish Gaelic
- Meaning: Black stream
- Pronunciation: DUG-lus
- Variations: Douglass, Dughlas
- Namesakes: General Douglas MacArthur
Douglas joins the Scottish Gaelic “dubh,” meaning “black” or “dark,” to “glas,” meaning “water” or “stream,” and it started as the name of a river before it named a powerful border clan.
American parents used it heavily through the 1940s, 50s, and 60s, helped along by General Douglas MacArthur. Today you will meet far more grandfathers named Douglas than babies, which is exactly the point for parents drawn to names with a little dust on them. Dougie and Duggie soften it considerably.
Doyle
- Origin: Irish Gaelic
- Meaning: Dark stranger
- Pronunciation: DOYL
- Variations: Doyl, Dowell, Dubhghall
Doyle traces to Dubhghall, with “dubh” meaning “dark” or “black” and “gall” meaning “stranger.”
Medieval Irish and English writers used Dubhghall for the Danish Vikings specifically, as opposed to the fair-haired Norwegians, so this mysterious name is really a piece of ninth-century ethnography.
The modern form is newer than the medieval genealogies suggest, and it went on to become one of the most common surnames in Ireland. American parents used it steadily for boys until the 1980s, so it is sitting right in the window where old names start looking new again.
Duane
- Origin: Irish Gaelic
- Meaning: Dark or swarthy
- Pronunciation: dwayn
- Variations: Dwayne, Dubhan, Dewayne
- Namesakes: Guitarists Duane Allman and Duane Eddy
Duane is the anglicized form of Dubhan, a name carried by the medieval saint who founded an abbey at Hook Head in County Wexford.
Its second life is far less monastic. Duane Allman and Duane Eddy put it on guitar necks and record sleeves, and punk singer Duane Peters kept it there. It has been out of use in both Ireland and the United States for two decades, which leaves it available for anyone who likes a name with a little grit in it.
Duncan
- Origin: Scottish Gaelic
- Meaning: Brown-haired warrior
- Pronunciation: DUN-kan
- Variations: Donnchadh
- Namesakes: King Duncan I of Scotland
Duncan is the anglicized form of the Scottish Gaelic Donnchadh, and it suits a boy with dark hair by definition.
Its earliest famous bearer, King Duncan I, was killed by Macbeth in 1040 and turned up 500 years later as the murdered king in Shakespeare’s play. Ireland used it heavily in the 1970s and 80s before more fashionable D names took over, and the United States picked it up in the early 2000s. It is friendly, it is unmistakably Scottish, and nobody has to ask how to spell it.
Eamon
- Origin: Irish Gaelic
- Meaning: Protector of riches
- Pronunciation: AY-mon
- Variations: Eamonn, Eamann, Edmond
- Namesakes: Eamon de Valera, president of Ireland
Eamon is the Irish Gaelic form of Edmond, a name meaning “protector of riches” from the Old English “ead,” meaning “prosperity,” and “mund,” meaning “protector.”
Ireland has used it consistently for a century, thanks in no small part to Eamon de Valera, who spent decades as taoiseach and then president. In the United States it barely registers, which makes it a quiet substitute for an Edmond that has been out of fashion since the 1980s.
Ennis
- Origin: Irish Gaelic
- Meaning: Island
- Pronunciation: EN-iss
- Variations: Innis, Inis
Ennis is a town in County Clare, and its name is a worn-down form of Inis Cluana Ramhfhada, “island of the long rowing meadow.” The island in question sits in the River Fergus, where the Franciscan friary was built in the 13th century. As a first name it is soft, short, and unfamiliar enough to feel found rather than chosen, and it makes a neat alternative to Dennis and Ellis.
Eoghan
- Origin: Irish Gaelic
- Meaning: Noble born
- Pronunciation: OH-un
- Variations: Eogan, Euan, Ewan, Owen
Eoghan is generally traced to the Latin Eugenes, meaning “high or noble born,” and its Gaelic spelling looks nothing like the way it sounds.
Ancient Ireland was full of them. Eogan mac Durthacht ruled Farney in the Ulster Cycle and stands as an enemy of King Conchobar mac Nessa, and the northern kingdom of Tir Eoghain still carries the name.
If the spelling worries you, Owen, Ewan, and Euan are all descended from it and are all far easier on a school form.
Ernan
- Origin: Irish Gaelic
- Meaning: Iron
- Pronunciation: AIR-nin
- Variations: Ernin, Ernain, Ernene
- Namesakes: Saint Ernan of Hinba, companion of Saint Columba
Ernan carries the sense of iron, and it is often treated as the Irish counterpart to the Germanic Ernest.
Several early Irish saints bore it, which is a remarkable concentration for a name most people have never heard. The best remembered is Ernan of Hinba, one of the twelve who sailed with Columba from Ireland to Iona. It is spare, strong, and completely unused today.
Farquhar
- Origin: Scottish Gaelic
- Meaning: Beloved man
- Pronunciation: FAR-kwar
- Variations: Farker, Farquher, Forker
Farquhar is a Scottish Gaelic surname built from “fear,” meaning “man,” and a second element read as “beloved” or “dear”; Farker, Farquher, and Forker are worn-down family variants of it.
Pronunciation varies by family and region, from far-kwar to far-ker to far-car, which is worth deciding before the birth certificate.
Farrell
- Origin: Irish Gaelic
- Meaning: Man of valor
- Pronunciation: FAR-el
- Variations: Farrel, Ferrell, Fearghal
Farrell is the anglicized form of O’Fearghail, with “fear” meaning “man” and “gal” meaning “valor.”
It was a normal American boy’s name until the 1960s and then slid quietly into the surname column, where it mostly still sits. That leaves this masculine name free for anyone who likes the sound of Darrell and Darryl but wants something with actual Irish footing behind it.
Fergus
- Origin: Irish and Scottish Gaelic
- Meaning: Man of vigor
- Pronunciation: FUR-gus
- Variations: Feargus, Fearghas, Ferghus
- Namesakes: Fergus mac Roich, king of Ulster in the Ulster Cycle
Fergus is built from “fear,” meaning “man,” and “gus,” meaning vigor or force, and it has never once sounded delicate.
Celtic myth gave it the perfect bearer. Fergus mac Roich was an enormous former king of Ulster, famous for his appetite, his sword Caladbolg, and his affair with Queen Medb of Connacht. His son Ciar gave his name to County Kerry.
Ferg, Fergie, and Gus all work as nicknames, and Gus in particular has become fashionable on its own.
Finley
- Origin: Scottish Gaelic
- Meaning: Fair warrior
- Pronunciation: FIN-lee
- Variations: Finlay, Findlay, Fionnlagh
Finley comes from the Scottish Gaelic Fionnlagh, joining “fionn,” meaning “white” or “fair,” to “laoch,” meaning “warrior” or “hero.”
American usage has tilted it toward girls, while in Ireland and Scotland it stays firmly a boy’s name. That split is worth knowing before you choose it. Finlay is the standard Scottish spelling, and Fin and Lee are both waiting as nicknames.
Forbes
- Origin: Scottish Gaelic
- Meaning: Field
- Pronunciation: FORBZ
Forbes takes its name from a district in Aberdeenshire, and clan legend says the founder, Oconachar, cleared the land of bears before claiming it.
In the United States the name reads differently. The Boston Forbes family and the business magazine give it money and polish rather than bears and heather.
Either association works in its favor. As a first name it is crisp, formal, and almost never used, which is the whole appeal.
Fraser
- Origin: Scottish Gaelic
- Meaning: Uncertain, possibly fruitful
- Pronunciation: FRAY-zer
- Variations: Frazer, Frasier, Fraiser
Fraser has resisted every attempt to pin it down. It may come from the Gaelic Frasach, meaning “the generous or fruitful one,” or from a lost Gaelic name that an Anglo-Norman scribe mangled beyond recovery.
Scotland treats it as an ordinary boy’s name, one of the great Highland clan names. Americans mostly know it through the sitcom Frasier, spelled with an extra i, which is either a help or a hindrance depending on how you feel about radio psychiatrists.
Galloway
- Origin: Scottish Gaelic
- Meaning: Place of the foreign Gaels
- Pronunciation: GAL-uh-way
- Variations: Galway, Gallaway
Galloway is a region in southwest Scotland, named for the mixed Norse and Gaelic people who settled there in the Middle Ages. Today it is a surname and a breed of shaggy black cattle, both of which give it a solid, outdoorsy feel. As a first name it is unfamiliar without being strange, and it shortens neatly to Gal or Loway.
Gilroy
- Origin: Irish Gaelic
- Meaning: Son of the red-haired man
- Pronunciation: GIL-roy
- Variations: Kilroy, McIlroy, Gilroe
Gilroy means “son of the red-haired man,” from the Irish surname Mac Giolla Ruaidh, built on “mac,” meaning “son,” and “ruadh,” meaning “red.”
It sits in the same sound family as Leroy and Elroy, which will read as charmingly retro or plainly dated depending on your ear. Gil and Roy are both usable on their own, and the name is a genuine fit for a red-headed baby with Irish grandparents.
Glenn
- Origin: Scottish and Irish Gaelic
- Meaning: Narrow valley
- Pronunciation: GLEN
- Variations: Glen, Glyn
Glenn comes from the Gaelic “gleann,” a narrow valley, and it began as a byname for people who lived in one.
That makes it a nature name that never announces itself as one. It ran strong in the United States from the 1920s through the 1970s, so it now carries a mid-century, shirt-and-tie quality. Names of that era have been returning steadily, and Glenn is short enough to survive the trip.
Grady
- Origin: Irish Gaelic
- Meaning: Noble or illustrious
- Pronunciation: GRAY-dee
- Variations: Gradey, O’Grady
Grady comes from the Irish “grada,” meaning “noble” or “high-born,” by way of the surname O’Grada. It has the same easy, two-syllable rhythm as Brady and Cody without being anywhere near as worn out. American parents have kept it in steady use for years without ever pushing it into the crowded end of the charts, which is close to the ideal position for a name.
Hogan
- Origin: Irish Gaelic
- Meaning: Youth
- Pronunciation: HOH-gan
- Variations: Hogain, O’Hogan
Hogan comes from the Middle Irish “ogan,” meaning “a youth,” so it is a name built for someone who will stay young at heart.
Irish Hogans trace themselves to the family of Brian Boru, the High King who broke Viking power at Clontarf, which is a strong claim for a name that mostly reads as easygoing. It sits one letter from Logan, a perennial American favorite, so it gives you a familiar sound that almost nobody else is using.
Ian
- Origin: Scottish Gaelic
- Meaning: God is gracious
- Pronunciation: EE-an
- Variations: Iain, Eaon, Ean
- Namesakes: Sir Ian McKellen and actor Ian Somerhalder
Ian is the Scottish Gaelic form of John, and it inherits the same meaning: God is gracious.
Three letters, no ambiguity, no nickname required. It has been an American favorite since the early 1980s, while Scotland itself has drifted toward longer options like Cian and Fabian.
Sir Ian McKellen and Vampire Diaries actor Ian Somerhalder cover both ends of its range, and Iain is the Scottish spelling if you want the extra i.
Keelan
- Origin: Irish Gaelic
- Meaning: Slender
- Pronunciation: KEE-lan
- Variations: Caolan, Kelan, Kealan
Keelan is the anglicized form of the Irish Caolan, from “caol,” meaning “slender” or “narrow.” Ireland has warmed to it steadily while the United States has barely noticed it, which is the sweet spot for parents who want a name that is proven but not popular. It also has the useful quality of being spelled the way it sounds, which cannot be said for most of its Gaelic cousins.
Kenneth
- Origin: Scottish Gaelic
- Meaning: Handsome or born of fire
- Pronunciation: KEN-eth
- Variations: Coinneach, Cinaed
- Namesakes: Director Kenneth Branagh
Kenneth anglicizes two separate Gaelic names, Coinneach, meaning “handsome,” and Cinaed, read as “born of fire,” which is how one name ended up with two meanings.
Cinaed mac Ailpin, remembered as Kenneth MacAlpin, is traditionally counted the first king of the Scots. That is roughly a thousand years of continuous use.
American parents kept it in the top ranks for the whole of the twentieth century, and it has cooled since without ever disappearing. Ken and Kenny are the obvious short forms, and Kenneth Branagh keeps the full version in circulation.
Kian
- Origin: Irish Gaelic
- Meaning: Ancient or enduring
- Pronunciation: KEE-an
- Variations: Cian, Kean, Keane
Kian is a variant spelling of the Irish Cian, and it happens to be a common Persian name as well, where it carries the sense of king.
That double heritage is unusual and genuinely useful for mixed families. In Ireland the traditional Cian dominates; in Scotland and the United States the K spelling is more common. Either way you get a short, warm name that non-Irish speakers can say correctly on the first try, which is rarer on this list than you might expect.
Kirwan
- Origin: Irish Gaelic
- Meaning: Little dark one
- Pronunciation: KUR-wahn
- Variations: Kirwin, Kerwin, Ciardubhain
Kirwan anglicizes the Old Gaelic Ciardubhain, which stacks two words for darkness, “ciar” and “dubh,” on top of each other.
The Kirwans were one of the Tribes of Galway, the merchant families who ran the city for centuries. As a first name it is almost unused, so it works as an unexpected route to the same sound as Kieran or Kaiden.
Kyle
- Origin: Scottish Gaelic
- Meaning: Narrow or strait
- Pronunciation: KYLE
- Variations: Kyler, Kile
- Namesakes: Actor Kyle MacLachlan
Kyle comes from the Gaelic “caol,” meaning “narrow” or “strait,” and it named several districts of southwest Scotland before it named anyone’s son.
It was an American heavyweight through the 1980s and 90s, which means most Kyles you meet are in their thirties. Technically it is unisex, though Kyla has taken over the girls’ side almost entirely. Twin Peaks star Kyle MacLachlan and NASCAR driver Kyle Busch keep it in front of very different audiences.
Lachlan
- Origin: Scottish Gaelic
- Meaning: From the land of the lochs
- Pronunciation: LOCK-lan
- Variations: Lochlann, Lachlann, Laughlin
Lachlan anglicizes the Old Gaelic Lochlann, a word medieval Irish writers used for Norway and, by extension, for the Vikings who came from it.
In the older literature Lochlann is a strange country over the water, half geography and half legend, which gives the name an atmosphere that plain nature names never manage.
Australia adopted it wholesale and it has climbed steadily in Scotland and the United States since. Lachie, Lachy, Locky, and Lockie are all in regular use, and Lachie in particular is hard to beat for a small boy.
Laisren
- Origin: Irish Gaelic
- Meaning: Flame
- Pronunciation: LASH-ren
- Variations: Lasrian, Molaise, Laserian
- Namesakes: Saint Laisren mac Nad Froich, one of the twelve apostles of Ireland
Laisren comes from the Irish “lasair,” meaning “fire” or “flame,” and the affectionate form Molaise means roughly “my Laisren.”
Early medieval Ireland was full of them, most of them monks. The best documented is Saint Laisren mac Nad Froich, counted among the twelve apostles of Ireland, who served under Saint Patrick. Lasrian and Laserian are the spellings you will find in older church records. Nothing about it is in current use, which is exactly why it is here.
Lennox
- Origin: Scottish Gaelic
- Meaning: Elm grove
- Pronunciation: LEN-ox
- Variations: Lenox, Lennix
Lennox comes from the Gaelic Leamhan, meaning elm, and names a district north of Glasgow still called the Lennox.
It is also a clan name, and the clan motto is “I’ll defend,” which is a decent thing to hand a child. The name has climbed hard in the United States and Scotland over the past decade, helped by its ring of x-ending names like Maddox and Jax. Lenox is the streamlined spelling if the double n feels heavy.
Liam
- Origin: Irish Gaelic
- Meaning: Resolute protector
- Pronunciation: LEE-am
- Variations: Uilliam, Liem, William
- Namesakes: Actor Liam Neeson
Liam is a shortened form of Uilliam, the Irish version of William, and it keeps William’s meaning of “strong protector.”
It became the single most used boys’ name in the United States in 2017 and has held the top of the charts ever since, so this is the one name on the list where you should assume there will be another one in the class. Ireland uses it heavily too.
Liam Neeson and Liam Payne between them cover the action-movie and boy-band ends of the name. If you love the sound but not the crowd, the full Uilliam is still there.
Logan
- Origin: Scottish Gaelic
- Meaning: Little hollow
- Pronunciation: LOH-gan
- Namesakes: Actor Logan Lerman
Logan is a Scottish surname taken from a place name in Ayrshire, and it comes from the Gaelic “lagan,” a little hollow.
It took off as a first name in the 1990s, held a place in the American top 20 through the 2010s, and is still a common pick, with Scotland running it even higher. Marvel fans will hear James “Logan” Howlett, better known as Wolverine, before they hear anything Gaelic. Logan Lerman gives it a gentler face.
Mac
- Origin: Irish and Scottish Gaelic
- Meaning: Son
- Pronunciation: MACK
- Variations: Mack
Mac is the Gaelic word for “son,” the building block behind hundreds of surnames from MacDonald to MacKenzie.
On its own it works as a stand-alone name or as a short form for Cormac, Macallister, or anything else beginning with the same sound. Mack is the more used spelling in the United States, and both carry a blunt, friendly, slightly old-fashioned quality. The truck and the computer are unavoidable associations, so pick your favorite.
Madden
- Origin: Irish Gaelic
- Meaning: Little dog
- Pronunciation: MAD-en
- Variations: Madigan, Madadhan
- Namesakes: NFL coach and broadcaster John Madden
Madden anglicizes the Gaelic Madadhan, from “madadh,” meaning “dog,” so it is a name for a boy you expect to be loyal and a little bit wild.
The O’Maddens ruled the territory of Silanchia in east Galway for centuries, which is more history than the name usually gets credit for. In an American house, though, it will always arrive attached to John Madden, the coach turned broadcaster whose video game franchise has outlived several console generations.
Malcolm
- Origin: Scottish Gaelic
- Meaning: Devotee of Saint Columba
- Pronunciation: MAL-kum
- Variations: Malcom, Maolcolm
- Namesakes: Malcolm X and Malcolm Young of AC/DC
Malcolm comes from the Scottish Gaelic Mael Coluim, joining “maol,” a word for a shaven-headed monk, to the name of Saint Columba: a devotee of Columba.
Four Scottish kings carried it. Malcolm III took the throne after defeating Macbeth, who had killed his father, which is the historical spine under Shakespeare’s play.
Its modern bearers pull in every direction at once: civil rights leader Malcolm X, AC/DC guitarist Malcolm Young, and writer Malcolm Gladwell. Malky is the Scottish diminutive, and Mal works anywhere.
Mannis
- Origin: Irish Gaelic
- Meaning: Great
- Pronunciation: MAN-iss
- Variations: Manus, Maghnus, Magnus
Mannis is the Gaelic form of the Latin Magnus, meaning “great,” which entered Ireland and Scotland through Norse contact. It doubles as a short form of the surname McManus. Manus is the spelling still used in Ireland; Mannis is rarer and reads as a quirkier alternative to double-n names like Dennis and Finneas.
Muir
- Origin: Scottish Gaelic
- Meaning: Sea or moorland
- Pronunciation: MYOOR
- Variations: Mure
- Namesakes: Naturalist John Muir
Muir means “sea” in Scottish Gaelic and “moorland” in Scots, so it comes with two landscapes attached.
Its best namesake earned the association honestly. John Muir, born in Dunbar, spent his life arguing for American wilderness protection and has a redwood forest in Northern California named for him. For a family that spends its weekends outdoors, few names are a neater fit.
Murray
- Origin: Scottish and Irish Gaelic
- Meaning: From the sea settlement
- Pronunciation: MUR-ee
- Variations: Murry, Moray, Muireadhaigh
Murray has two roots that ended up in the same place. In Ireland it comes from O’Muireadhaigh; in Scotland it anglicizes Moray, the great northern province whose name traces to a Celtic word for a settlement by the sea.
Scotland still uses it as a first name, helped along by a certain tennis player, while in the United States it has been out of the nursery since the 1920s. That leaves it squarely in grandfather territory, which is exactly where the next wave of comebacks tends to come from.
Nevin
- Origin: Irish and Scottish Gaelic
- Meaning: Little saint or little bone
- Pronunciation: NEV-in
- Variations: Nevan, Niven, Naomhan
Nevin has a split personality. The Irish Cnamhin means “small-boned,” a byname for a slight man, while the Scottish Gaelic Naomhan means “little saint.”
Take your pick; both are sourced and neither is grim. As a name it does what Devin and Kevin do without carrying either one’s decade. Nev and Vin are the natural short forms.
Niall
- Origin: Irish Gaelic
- Meaning: Uncertain, often given as champion
- Pronunciation: NYE-al
- Variations: Neil, Neal, Niallan
- Namesakes: Niall Horan of One Direction
Niall is genuinely old enough that scholars cannot agree on what it meant. The usual gloss is “champion,” from the Old Irish “niadh,” but a University College Dublin professor has pointed out that the meaning appears to have been lost before written records began.
Its most famous bearer is Niall of the Nine Hostages, the fifth-century High King whose Y-chromosome lineage turns up in a striking share of men in northwest Ireland today.
Modern listeners will think first of Niall Horan of One Direction. Neil and Neal are its anglicized descendants, and both are far easier to say on the first attempt: the Irish original is closer to NYE-al than to Neil.
Nolan
- Origin: Irish Gaelic
- Meaning: Descendant of the noble one
- Pronunciation: NOH-lan
- Variations: Nolen, Nolin, Nuallain
- Namesakes: Pitcher Nolan Ryan
Nolan comes from the Irish O’Nuallain, built on “nuall,” a word for a shout or a champion, which is where the “noble” and “famous” readings both come from.
There is a neat irony in it: Nolan is a solid performer in the United States and Scotland while Ireland, where it originated, has almost stopped using it as a first name. Hall of Fame pitcher Nolan Ryan and Modern Family’s Nolan Gould give it a wholesome, all-American face that suits it well.
Odhran
- Origin: Irish Gaelic
- Meaning: Little dun one
- Pronunciation: OR-an
- Variations: Odran, Oran, Orin
- Namesakes: Saint Odran, charioteer to Saint Patrick
Odhran comes from “odhar,” meaning dun or pale, plus the diminutive “-an,” so the literal sense is little pale one rather than anything greener.
Two early saints carry it: Odran, remembered as Saint Patrick’s charioteer, and Odran of Iona, one of the companions who helped Columba plant Christianity in Scotland. The feminine form is Odharnait.
Ireland uses it heavily today, and the spellings Oran and Orin are there if you would rather not explain the silent dh at every appointment.
Oisin
- Origin: Irish Gaelic
- Meaning: Little deer
- Pronunciation: oh-SHEEN
- Variations: Oisean, Ossian, Osheen
Among our many Irish boy names inspired by nature, Oisin means “little deer,” from the Irish “os,” meaning deer, plus the diminutive ending.
The mythology behind it is one of the saddest in Irish literature. Oisin, warrior and poet of the Fianna, fell in love with the fairy Niamh and lived with her in Tir na nOg for what felt like three years. When homesickness took him back to Ireland, three centuries had passed. He was warned not to touch the ground, stopped to help some men move a stone, slipped from his horse, and aged three hundred years in an instant.
Oisean is the Scottish Gaelic spelling, and Ossian and Osheen are the anglicizations. None of them prepares an American reader for oh-SHEEN, so expect to say it twice.
Peadar
- Origin: Irish and Scottish Gaelic
- Meaning: Rock
- Pronunciation: PAD-ur
- Variations: Peader, Peter, Padar
- Namesakes: Peadar Kearney, who wrote the lyrics of Ireland’s national anthem
Peadar is the Irish and Scottish Gaelic form of Peter, from the Greek “petros,” meaning “rock.”
Irish namesakes are plentiful. Peadar Kearney wrote the lyrics to Amhran na bhFiann, Ireland’s national anthem, and Peadar Ua Laoghaire’s novel Seadna is a founding text of modern Irish prose.
Scottish Gaelic tradition largely reserved the name for the apostle himself, which is why Scotland has so few Peadars while Ireland has kept the name in steady use for generations.
Quade
- Origin: Irish Gaelic
- Meaning: Son of Uad
- Pronunciation: KWAYD
- Variations: Quaid, McQuaid, Quaide
- Namesakes: Rugby player Quade Cooper
Quade is a reduced form of the Irish McQuaid, meaning “son of Uad.”
Be aware that the same string of letters means something far less friendly in German, where it was a nickname for a wicked man. That has not stopped anyone. Opera composer Quade Winter and Australian rugby fly-half Quade Cooper both wear it, and it makes a sharper alternative to Wade or Cade.
Quinn
- Origin: Irish Gaelic
- Meaning: Descendant of Conn
- Pronunciation: KWIN
- Variations: Quin, Cuinn
Quinn comes from the surname O’Cuinn, built on “conn,” a word carrying the sense of chief, counsel, or intelligence.
It is one of the genuinely successful gender-neutral names, used for boys and girls across Ireland, Scotland, and the United States without ever landing hard on one side. This “Q” name also works as a short form of Quinton or Quincy if you want a longer name on the certificate.
Rafferty
- Origin: Irish Gaelic
- Meaning: Prosperity
- Pronunciation: RAF-er-tee
- Variations: Rabhartaigh
Rafferty anglicizes the Irish surname O’Rabhartaigh, and as a personal name it draws on the Old Irish “rath,” meaning “prosperity” or “abundance.” Three syllables give it a bounce that most Gaelic surnames-turned-names do not have, and Rafe and Raff are both excellent short forms. It has the feel of a name a novelist would invent, with the advantage of being entirely real.
Ragnall
- Origin: Scottish and Irish Gaelic
- Meaning: Ruler of the gods
- Pronunciation: RAG-nal
- Variations: Ranald, Rannal, Ronald
- Namesakes: Ragnall ua Imair, tenth-century king of York
Ragnall is the Gaelic form of the Old Norse Rognvaldr, joining “regin,” meaning “gods,” to “valdr,” meaning “ruler,” and it arrived in Ireland and Scotland with the Vikings.
Ragnall ua Imair, grandson of Ivar, fought Constantin mac Aeda of Scotland and made himself king of York in the tenth century. Ranald and Rannal are the Scottish anglicizations, and Ronald is where the whole line eventually ended up.
Ray
- Origin: Scottish Gaelic
- Meaning: Son of grace
- Pronunciation: RAY
- Variations: Rae, Rea, Raymond
- Namesakes: Singer Ray Charles
Ray comes from the Scottish Mac Raith, meaning “son of grace,” though it has separate English, French, and Ashkenazi Jewish lines as well.
Nobody will hear the Gaelic first. They will hear a ray of sunshine, or Ray Charles at a piano, or Ray Romano on a sitcom. As a stand-alone first name rather than a short form of Raymond, it is having a quiet revival among parents who like one-syllable names.
Rian
- Origin: Irish Gaelic
- Meaning: Little king
- Pronunciation: REE-an
- Variations: Ryan, Rion, Ryen
Rian is old enough that its meaning is contested. Some scholars read the Gaelic “rian” as “ocean” or a course across water; others take it from “ri,” meaning “king,” with a diminutive ending.
Whatever the origin, it is thriving in Ireland, where the Gaelic spelling now competes seriously with its English descendant. That descendant, Ryan, has been an American staple for fifty years. Rian gives you the identical sound with a spelling that points home.
Ronan
- Origin: Irish Gaelic
- Meaning: Little seal
- Pronunciation: ROH-nan
- Variations: Ronin, Ronain
- Namesakes: Singer Ronan Keating and writer Ronan Farrow
Ronan comes from the Irish “ron,” meaning seal, and the name is old enough to appear in Primitive Irish ogham inscriptions.
Irish legend gives it a selkie: a seal woman swept ashore who takes human form, marries a fisherman, and bears children called ronans, little seals. She eventually finds her sealskin and returns to the water, but she stays near the shore watching her family.
Several saints wore it too, including Ronan of Locronan in Brittany and Ronan of Iona, who argued the Easter dating question settled at the Synod of Whitby in 664. Boyzone singer Ronan Keating and writer Ronan Farrow keep it current.
Rooney
- Origin: Irish Gaelic
- Meaning: Descendant of the champion
- Pronunciation: ROO-nee
- Variations: Ruane, Ruanaidh
Rooney anglicizes the Irish surname O’Ruanaidh, from a root meaning champion or hero. It has been a last name for so long that using it up front feels almost playful, which is the point. It sits alongside Clooney and Mooney in the double-o family, and Rune and Roone both work as short forms.
Rory
- Origin: Irish and Scottish Gaelic
- Meaning: Red king
- Pronunciation: ROR-ee
- Variations: Ruairi, Ruaidhri, Rori
- Namesakes: Golfer Rory McIlroy and guitarist Rory Gallagher
Rory comes from the Gaelic Ruaidhri, joining “ruadh,” meaning red-haired, to “ri,” meaning king. Ruaidri Ua Conchobair was the last High King of Ireland before the Norman invasion.
It is technically unisex, and Gilmore Girls gave the girls’ side a long run, but it remains a boys’ name in Ireland and Scotland. Blues guitarist Rory Gallagher and golfer Rory McIlroy both make the case.
If you want the full Irish spelling, Ruairi and Ruaidhri are both in use, though neither is kind to an American substitute teacher.
Ross
- Origin: Scottish Gaelic
- Meaning: Headland or promontory
- Pronunciation: ROSS
- Variations: Ros
Ross comes from the Gaelic “ros,” a headland or a spit of land jutting into water, and it names a county in the Scottish Highlands.
The nature reading is real, not invented: this is a landscape name in the same family as Muir and Glenn. American parents of a certain age will hear the paleontologist from Friends first, which has done the name no lasting harm. One syllable, no spelling questions, works with almost any surname.
Sean
- Origin: Irish Gaelic
- Meaning: God is gracious
- Pronunciation: SHAWN
- Variations: Seann, Shaun, Shawn, Shane
Sean is the Irish form of John, and it carries the same meaning: God is gracious.
Irish has no letter J, so when the Norman French brought Jean to Ireland it was respelled to fit Gaelic sounds, and Sean is the result. That single spelling decision is why so many English speakers meet the name and say it wrong the first time.
Shaun, Shawn, Shane, and Shayne all descend from the same source. Sean itself has cooled in the United States since its 1990s peak while holding steady in Ireland, which puts it in the comfortable middle: familiar, not fashionable.
Senan
- Origin: Irish Gaelic
- Meaning: Little wise one
- Pronunciation: SHEN-an
- Variations: Seanan, Sennan, Sinan
- Namesakes: Saint Senan mac Geircinn, founder of the Scattery Island monastery
Senan comes from the Irish “sean,” meaning old, with a diminutive ending, so the sense is a little old one, or a wise one.
Senan mac Geircinn founded the monastery on Scattery Island in the Shannon estuary in the sixth century, and the ruins are still there. Ireland has taken the name up again in a serious way while the United States has never used it, which makes it an Old Irish name with a modern feel and a fresher route to the same sound as Sean.
Shaw
- Origin: Scottish Gaelic
- Meaning: Wolf
- Pronunciation: SHAW
- Variations: Shawe, Sitheach
- Namesakes: Former Salvation Army general Shaw Clifton
Shaw descends from the Gaelic name Sitheach, meaning wolf, and separately from an English word for a thicket or small wood.
Clan Shaw is one of the old Highland families of Strathspey. Mostly the name still works as a surname used occasionally up front, worn by British broadcaster Shaw Taylor and Salvation Army general Shaw Clifton. Its real strength is as a one-syllable middle name, where it braces a longer Gaelic first name without competing with it.
Sheehan
- Origin: Irish Gaelic
- Meaning: Peaceful one
- Pronunciation: SHEE-an
- Variations: Sheahan, Sheahon, Siochain
Sheehan anglicizes the Gaelic O’Siochain, from “siochain,” meaning peace. It first appears among the Irish clans in the tenth century, most likely attached to a man known for keeping the peace rather than breaking it, whether a priest or a warrior inclined toward settlement. Sheehan and Sheahan are both common surnames in Ireland today, and either makes an unexpected, gentle first name.
Sheridan
- Origin: Irish Gaelic
- Meaning: Searcher
- Pronunciation: SHER-i-dan
- Variations: Siridean
- Namesakes: Gothic novelist Sheridan Le Fanu
Sheridan comes from the surname O’Sirideain, “descendant of Siridean,” and as a personal name it draws on the Gaelic “sirim,” meaning to seek or search.
It splits cleanly into Sheri for a girl and Dan for a boy, which is part of why it works so well as a gender-neutral choice. Sheridan Le Fanu, the nineteenth-century master of the Irish ghost story, is its best namesake, and Irish composer Sheridan Tongue is its most recent.
Sloane
- Origin: Irish Gaelic
- Meaning: Raider
- Pronunciation: SLOHN
- Variations: Sloan, Slone, Slaughadain
Sloane anglicizes the surname O’Slaughhadain, built on “sluaghadh,” meaning a raid or a military expedition.
American usage has swung hard toward girls in the past decade, but the name has never actually left the boys’ side. Film director Sloan Copeland and actor Sloane Morgan Siegel both keep it there. If you like the sound and are not bothered by the trend, it is a genuinely unisex option with a fierce meaning behind a smooth surface.
Sorley
- Origin: Scottish Gaelic
- Meaning: Summer traveller
- Pronunciation: SOR-lee
- Variations: Somhairle, Somerled, Sorly
- Namesakes: Poet Sorley MacLean
Sorley anglicizes the Scottish Gaelic Somhairle, itself from the Old Norse Sumarlidr, meaning summer traveller, a byname for Vikings who raided in the warm months and went home for winter. The word sumarlida turns up in the Anglo-Saxon Chronicle as early as 871.
Somerled, Lord of Argyll, drove the Norse out of the Hebrides before his death in 1164 and founded the line that became Clan Donald. Sorley Boy MacDonnell fought the English crown in Ulster four centuries later.
The best modern bearer is Sorley MacLean, whose Gaelic poetry is among the finest written in Scotland in the twentieth century. It is sometimes anglicized as Samuel, though the two names share nothing at all.
Tadhg
- Origin: Irish and Scottish Gaelic
- Meaning: Poet or philosopher
- Pronunciation: TYGE
- Variations: Tadgh, Teague, Tighe
- Namesakes: Rugby players Tadhg Furlong and Tadhg Beirne
Tadhg means “poet” or “philosopher,” from the Proto-Celtic root tazgj-o-, and it is pronounced TYGE, rhyming with the first syllable of tiger.
Irish kings carried it between the tenth and sixteenth centuries, and it has staged one of the most remarkable comebacks of any Irish name: it stood at 92nd for Irish boys in 2000 and reached 7th by 2022 (2).
American parents have left it alone, almost certainly because the spelling gives no clue to the sound. Teague and Tighe are the anglicizations if you want the name without the daily explanation, but Ireland’s rugby team has two prominent Tadhgs and neither seems slowed down by it.
Trevor
- Origin: Welsh and Irish Gaelic
- Meaning: Large homestead, or prudent
- Pronunciation: TREV-ur
- Variations: Trefor, Trevar, Treabhair
- Namesakes: Skateboarder Trevor Colden
Trevor has two separate origins that happen to land on the same spelling. In Welsh it comes from “tref,” meaning homestead, and “fawr,” meaning large. In Irish it anglicizes O’Treabhair, carrying the sense of prudent or industrious.
It was an American staple through the 1990s and early 2000s, which gives it the particular warmth of a name your slightly older cousin had. Skateboarder Trevor Colden and Grown-ish actor Trevor Jackson are its most visible young bearers.
Tully
- Origin: Irish Gaelic
- Meaning: Flood or peaceful one
- Pronunciation: TULL-ee
- Variations: Tulley, Tullie, Taithligh
Tully descends from a cluster of Old Irish surnames, O’Taithligh, O’Maoltuile, and Mac Maoltuile, and its meaning depends on which one you follow.
It may come from “tuile,” meaning flood, or from “taithleach,” meaning peaceful. Whether your baby turns out calm as a lake or unstoppable as a river in spate, one of the two readings will fit. It also has the rare quality of sounding equally at home on a toddler and a grown man.
Tynan
- Origin: Irish Gaelic
- Meaning: Dark
- Pronunciation: TY-nan
- Variations: Tivnan, Tynnan
Tynan comes from the Gaelic O’Teimhneain, with “teimhean” meaning dark or dusky. It gives you the same opening sound as Tyler, Tyrone, and Tyson without the crowd that comes with any of them, and it has an Irish surname’s solidity behind it. Ty is the obvious nickname and needs no explanation at all.
Whelan
- Origin: Irish Gaelic
- Meaning: Little wolf
- Pronunciation: WAY-lan
- Variations: Whelehan
Whelan anglicizes the Gaelic O’Faolain, from “faol,” meaning wolf, with a diminutive ending.
Pronunciation shifts across Ireland, from fay-lan to way-lan, which is worth settling early. This cool animal-inspired name sits in the same sound family as Callan, Declan, Lachlan, and Nolan, and it is by far the least used of the group.
