A spelling variation of Evelyn for those who prefer the Irish form. Little Aibhilins might have to explain how to pronounce their name, but some may feel that it's worth it to choose a unique option.

Aibhilin

Aidan is an ancient Irish saint's name with a fire meaning that's mega popular for boys, most often spelled as Aiden. The name is occasionally used for girls, sometimes as Aidyn or Ayden, as well. Aidan was the name of a famous seventh-century Irish saint, and is related to the Irish word for fire.

Aidan

Aidan was originally a pet form of the Irish name Aodh (pronounced 'ee'), the name of the old Celtic god of the sun and fire. The name was borne by numerous early Irish saints, one of whom was noted for his kindness and generosity. 
 
Aidan is an appealing Irish saint's name meaning fire that zoomed up the popularity lists, jumping four hundred places in a decade to a peak of 39 in 2013 before slumping down. Though it has been overtaken by variant spelling Aiden, the original Aidan is worth considering before selecting one of its offshoots: Caden, Brayden, et al.
 
Aidan was first introduced into the mainstream American consciousness by actor Aidan Quinn, and was given a definite bounce by the appealing Aidan on Sex and the City. Aidan has many variations, among them, Aiden, Aden, Adan, Aedan, and Ayden.

This attractive and unique Scottish form of Alice can also be found in the spelling Aileas. Like Alice, it ultimately derives from the Germanic name Adalheidis. Spelt with the fada, Ailís, it's Irish and pronounced with a longer final vowel: AY-leesh.

Ailis

Aimiliona

More commonly seen here as Anya, this traditional yet unique Irish name belonged to the queen of the Munster fairies and is sprinkled throughout Irish folklore as an early Celtic goddess of summer and prosperity. One of the most <a href="https://nameberry.com/popular-names">popular baby names</a> in Ireland, Aine's spelling and pronunciation might seem simple but could prove confusing in the U.S.
 When the British cracked down on authentic Irish names in the seventeenth century, Aine was "translated" as Ann. Now, the original Aine or Anya is one of the prime <a href="https://nameberry.com/list/433/goddess-baby-names">goddess names</a> for baby girls.

Aine

Aisling is currently a very popular <a href="https://nameberry.com/baby-names/509/irish-names-for-girls">Irish name for girls</a>. Pronounced variously as ASH-ling, ASH-lin or ash-LEEN, it was part of the revival of authentic <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> in the twentieth century, and is now being sparingly used by U.S. parents in place of the dated Ashley--though often spelled phonetically as Ashlyn or Ashlynn.
 An aisling is a poetic genre that developed in late seventeenth century Ireland, a type of patriotic-romantic poetry in which Ireland is addressed as a beautiful woman.

Aisling

Old Irish name that's taken off in its Anglicized forms, mainly Ashlyn or Ashlynn. Nonetheless, this more traditional version debuted in the US Top 1000 in 2015.
 Aislinn Paul is a Canadian actress known for her role of Clare Edwards in Degrassi: The Next Generation.

Aislinn

In its three most popular spellings -- Alan along with Allen and Allan -- this midcentury favorite has tended to skew older. It was a Top 100 name from 1938 to 1971, peaking at Number 40 in 1951. Alan has had leading roles on recent TV, in shows like Two and a Half Men, 24 and Boston Legal.
 Current bearers include Alan Alda, Alan Cummings, and writers Alan Bennett and Alan Ayckbourn.
Alan is a venerable Celtic name, first used in England in the Middle Ages. We like the Welsh spelling Alun.

Alan

This feminine form of Arliss, is familiar via the recent HBO series. But why not just use Arliss? 

Arlise

This name of an ancient Irish saint -- a favorite disciple of Saint Patrick -- could be an option for parents in search of a more distinctive alternative to Brendan or Aidan. 

Benen

This Irish name of a saint from the Isle of Aran also appears in myth and fantasy fiction, giving it an intriguing, mystical air. 
 Some modern parents are attempting to update the spelling, as in the actor Breckin (middle name Erin) Meyer or the most popular form of the name, Brecken.

Breccan

Brona is an Anglicized form of Bronach or Bronagh, the name of a sixth century mystic and follower of Saint Patrick. The name is attracting some modern notice in the US via the character Brona Croft in TV's Penny Dreadful.

Brona

Caiside

An Irish and Welsh form of Catherine, Caitlin was a boom name of the eighties, rocketing from obscurity (Americans first heard it via the wife of doomed poet Dylan Thomas) to the height of popularity in the space of a decade. The original name was gradually eclipsed by its myriad spelling variations -- Katelyn and Kaitlyn both soon topping it on the popularity lists.
 Now, most forms of Caitlin, including this most-authentic one, have started to dip, though there have been thousands of girls named Caitlin -- and Katelyn and Kaitlyn ad infinitum -- every year for the past three decades. So, while Caitlin is certainly one of the loveliest variations of Catherine, it's been overused to the point of semi-retirement, at least in the U.S. Cait might be a short form.
 Actor Breckin Meyer named his daughter Caitlin in 2003. Caitlyn Jenner also brought a renewed fame to the name, though she uses the -lyn variation.

Caitlin

A beaming, friendly Irish last-name-first-name waiting to be discovered. 

Calhoun

A classic Irish "top-o'-the-mornin' surname with a lot of rhythm and pizzazz. 

Callaghan

Stronger and more contemporary twist on Carla or Carly, Carlin was used just about equally for girls and boys in the US last year.

Carlin

Carson is one of the most long-running popular <a href="https://nameberry.com/unisex-names">androgynous baby names</a>, with a dash of the Wild West via the legendary Missouri frontiersman Kit Carson. Dating back to when it was the name of Nancy Drew's Dad, Carson is still steadily in the Top 200 <a href="https://nameberry.com">baby names</a>.
Current Carsons include TV personalities Carson Daly and Carson Kressley, and Pro Bowl quarterback Carson Palmer. Carson Wells was the bounty hunter character played by Woody Harrelson in No Country for Old Men, and Carson is the name chosen by actress Kathryn Erbe for her son.
 Although its best known namesake is writer Carson McCullers, Carson has not caught on as a <a href="https://nameberry.com/girls-names">girl's name</a>.

Carson

Cashel is one of the many appealing <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> that have not yet emigrated to the US. Cashel was chosen by actor Daniel Day-Lewis and his writer-director wife Rebecca Miller for their son. 
 In Ireland, Cashel refers to a circular stone fort. It is the name of a town in Tipperary and the protagonist of the George Bernard Shaw novel Cashel Byron's Profession.
 The Cash sound feels especially contemporary and appealing now, with Cashel joining such stylish brothers as Cassius, Cassian, and Cash.

Cashel

Ciara is very popular in Ireland, more familiar here as the Anglicized Kiera or Keira. The uninitiated will tend to pronounce Ciara as the Italian Chiara, a form of Claire—kee-AHR-a or even see-AHR-a, like the American singer-songwriter Ciara. In the US, Ciara peaked in 2005, when it was the Number 150 name; it's since fallen down to Number 882.

Ciara

Attached in Irish mythology to a Cliona who was, among other things, an inspirer of poets. Cliona is well-used in modern Ireland, along with Irish form Cliodhna, though it's largely unknown in the rest of the world.

Cliona

Thanks to its dashing Anglo-Irish image — due partly to Colins Firth and Farrell — and its C-initialed two-syllable sound, Colin and its cousin Collin have enjoyed a long run of popularity, reaching as high as Number 84 in 2004. 
 The usual pronunciation of Colin is COLL-in, but the alternate COLE-in version was publicized by General Colin Powell, the first U.S. African-American Secretary of State, who was named after World War II hero Colin Kelly.
 Literary cred: Colin Craven is a character in The Secret Garden, and Colin Creevey appears in the Harry Potter books.
 Both Kevin James and Kiss's Paul Stanley have young sons named Colin, while Tom Hanks has a grown one.

Colin

If there are too many Connors in your neighborhood, this name is equally authentic and much more unusual. Spelled Conal or Conall, it's a prominent name in Irish history, borne by a number of kings and heroes.

Conal

Conlan

Cordelia is exactly the kind of old-fashioned, grown-up name for girls that many parents are seeking for their daughters today. The name of King Lear's one sympathetic daughter, Cordelia has both style and substance along with its Shakespearean pedigree.
 <br/
Cordelia is a Nameberry favorite—Number 106 on the site—and it reentered the US Top 1000 in 2014 after a 60+ year absence. By 2016 it sank below that line again, must to the relief of many Cordelia fans who feared the name would get too popular.
 
If you're torn between Cordelia and the equally lovely Cora, you can always choose Cordelia for long and then call her Cora for short—or Delia, Lia, Del, or even the extremely different Cordie.
 Cordelia also appeared in Evelyn Waugh's Brideshead Revisited, Margaret Atwood's Cat's Eye, as detective Cordelia Gray in P.D. James's mystery novels, and was promoted by a character on both Buffy the Vampire Slayer and its spin-off Angel.
 And then there's that quote from the heroine of Anne of Green Gables: "I would love to be called Cordelia. It's such a perfectly elegant name."

Cordelia

Both offbeat and upbeat, this evocative traditional Irish name that runs through Celtic mythology is known here via award-winning novelist Cormac McCarthy (born Charles). The author's adopted name is related to Cormac Mac Airt, one of the great legendary high kings of Ireland.
 In two of the Harry Potter movies, Cormac McLaggen is a Gryffindor student.
 And for all you popularity-phobes, Cormac has never yet made it onto the American Top 1000 list.

Cormac

Sadly, this strong Celtic name often has "of the sorrows" attached to it because of the tragic character in Irish legend. Also a bit drab when compared with newer Irish imports. 

Deirdre

Dellaney

Irish Gaelic form of Evelyn or Aveline, more authentically spelled Eibhlín.

Eibhlin

Familiar in the US thanks to the lovely movie Brooklyn, based on the Colm Toibin novel of the same name. Popular in medieval times, it is still used in Ireland (properly spelt with a fada: Eilís) could make an alternative to the super-popular Isla. Eilish and Eibhlis are alternate forms.

Eilis

Popular name in Ireland -- it's pronounced ee-mer -- from the legendary wife of Cuchulainn who was supposed to possess the six gifts of womanhood: beauty, voice, speech, wisdom, chastity, and of course, needlework. Is found in the poetry of Yeats.

Emer

First-wave Irish name and place name—the poetic name for Ireland—now supplanted by newer alternatives such as Maeve and Delaney. 

Erin

Fia may be most notable at this moment as the Anglicized version of the Irish Fiadh, one of the fastest-rising names in the Republic of Ireland. The meaning of Fia or Fiadh is sometimes given as "deer" but that's in the sense of a wild deer, as the name relates to the ancient word for wild. 

In Portuguese, Fia means weaver, and Fia may also be a short form of the Italian or Spanish Sofia or Fiammetta or any other fia-related name.

Whatever its origin and meaning, Fia is a light and pleasant alternative to the mega-popular Mia.

Fiadh is the fastest-rising girls' name in Ireland, derived from the ancient root word for "wild". The Anglicized form Fia is one we might see rising in the US as well – to take the place of its popular cousin Mia.

Fiadh

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity. 
 Finn was chosen by cool couple Christy Turlington and Ed Burns for their son, and also by Jane Leeves and Autumn Reeser. Played by Cory Monteith prior to his death, Finn Hudson was a prominent character on Glee.
Other up-and-comers in the same family: Finlay and Finley, Finian and Finnian, Finnegan and Finnigan, and, from Germany, Fynn.

Finn

Finnigan is another way to spell Finnegan, one of the energetic Irish surname-names in vogue now. One note: While Finnigan, Finnian, Finley and so on are appealing names on their own, you don't need to use a longer form to get to Finn, which is a perfectly proper name all on its own.

Finnigan

Fintan is an ancient Irish saints' name that in legend is also the name of the only person to survive The Flood.  Popular in modern Ireland, Fintan is ripe for export to the US where it is rarely used but could make an excellent long form for the stylish Finn.

Fintan

Any number of Fitz names -- Fitzgerald, Fitzpatrick, Fitzroy, Fitzwilliam -- have been used as Christian names, in fact Fitzwilliam was the given name of the dashing Mr. Darcy in Pride and Prejudice. Fitz can be a short form of any of them and is often, like Mac, a nickname drawn from a surname.

Fitz

A common surname in Ireland, often use as an anglicization of Mac Giolla Phádraig. This name could honor a Patrick. It's also a way to get to Fitz as a nickname.

Fitzpatrick

Gallagher is, like so many of its genre, friendly, open, and optimistic. Some might associate it with the fraternal members of the band Oasis, Noel and Liam Gallagher.


Gallagher

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.
 
Though never in the American Top 1000, Imogen may be more popular in your hip neighborhood than that statistic would suggest. A contemporary classic in England and Wales, Imogen has ranked in the Top 100 ever since detailed naming records began in 1996. It's also a Nameberry favorite, consistently among the Top 100 most viewed girl names on our site.
 
The story goes that Imogen originated as a Shakespearean printer's misspelling of the traditional Celtic name Innogen, used by him for a character in one of his last plays, Cymbeline. The Innogen of legend, who Shakespeare’s character was based on, was the wife of Brutus of Troy, the first king of Britain. Earlier versions of her name, including Ennoguent, Innoguend, and Innoguent, were found in Brittany from the 9th-11th centuries. They are probably derived from the Gaelic word inghean, meaning "daughter" or "maiden," and possibly have a connection to the Proto-Celtic word for "white," from which the suffixes -gwyn and -gwen evolved.
 
Even if Shakespeare did happen upon Imogen by accident, he wasn't the first person to use the name. The Latin name Imogenis, meaning "lowest-born," existed centuries before Shakespeare, and was first recorded in the 13th century.
 Imogen gained attention in recent times through its link to Grammy-winning musician Imogen Heap. Other pluses: Imogen has the wonderful namesake photographer Imogen Cunningham and also a meaning that can't be topped. Immy is the cute diminutive; in the book and movie Fried Green Tomatoes, the character Imogene's nickname was Idgie.

Imogen

This attractive surname name still projects that Kennedy family charisma. While it didn't come into widespread use until long after the deaths of martyred heroes President John F. or Senator Robert Kennedy, Kennedy is now one of the most <a href="https://nameberry.com/unisex-names">popular unisex names</a> for girls as well as the top <a href="https://nameberry.com/search/girls-names/k">girls' name starting with K</a>. This is one name that manages to sound trendy and classic at the same time.

Kennedy

Kiera entered the American popularity list in 1988, though it lags behind the alternate spelling Keira, largely due to the fame of actress Keira Knightley. 
 The original Irish spelling is Ciara, the name of an early saint (who was said to have put out fires by the power of her prayer) which was the most popular name in Ireland a couple of decades ago.
 Keira is the more popular spelling, but Kiera is the more authentic--though both have pretty mush lost their Irish accents. There is also the male Kieran.

Kiera

Pronounced lee-sha, Laoise is the feminine form of the Irish mythological names Lugh and Lugus, which means light. Lugus was the Celtic god of commerce and craftsmanship, the equivalent of the Roman Mercury, thought to inspire the later Irish hero Lugh. Laoise is among the Top 100 <a href="https://nameberry.com/baby-names/509/irish-names-for-girls">Irish names for girls</a>, but Americans will definitely have pronunciation issues.

Laoise

While Larkin takes this name from girlish bird to boyish surname, there are actually more female Larkins these days than male, and it's a name that works as well for either gender.

Larkin

Conjures up pleasant images of lakes, but the pronunciation challenge makes the Anglicized Loughlin preferable. 

Lochlainn

Lochlann

This name of several early Irish saints makes a nice Logan/Conan alternative. 

Lonan

Lorcan is a name rich in Irish history as belonging to several kings, including the grandfather of the most famous high king of Ireland, Brian Boru. Lorcan O'Toole, known in English as Laurence O'Toole, is the patron saint of Dublin, so it's not too surprising that Irish-born actor Peter O'Toole named his son Lorcan.
 In the Harry Potter epic, Lorcan is the twin son of Luna Lovegood Scamander.
 Strong, easy to pronounce and spell, Lorcan is an Irish name that would stand out from the more common crop of Connors and Liams.

Lorcan

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel. Mack entered the popularity list in 2009 for the first time since 1989 and continues to climb. However, it's still far from its peak — it was a Top 100 name in 1900.
 Mack (born Michael) Sennett was the innovator of slapstick comedy in silent films. The name is also suggestive of Mack the Knife and a whole family of computers. Kevin Kline, Cuba Gooding, Jr., Dan Aykroyd, Eric Roberts and Snoop Dogg have all played characters named Mack.

Mack

Madden is an Irish surname relative of Madigan rising through the charts thanks to its trendy two-syllable, -en ending sound along with its appeal to Madden Football video game-playing dads.  John Madden is a former pro football player who went on to coach the Oakland Raiders and become a popular NFL commentator. Madden is also the surname of groovy Nicole Richie baby daddy Joel Madden.

Madden

Maeve is a short and sweet name that has become one of the most stylish Irish names for girls in the modern US. Maeve would make an excellent first or middle name choice, with more heft than Mae/May and more modern charm than Mavis. 
 Maeve appears in Irish mythology in two forms, one as the powerful Queen of Connacht, the other as the queen of the fairies. Maeve of Connacht was a warrior queen, famous for starting a war in attempt to steal her ex-husband’s stud bull. Other spellings are Meabh, Medb and Meadhbh, which are connected to mead, a honey-based wine that was produced in many ancient cultures.
 
Chris O'Donnell, Lili Taylor and Kathryn Erbe used Maeve for their daughters. The Irish author Maeve Binchy also is a well-known bearer. Maeve is the name of one of the lead characters on the HBO show Westworld.
 Irish spelling Meabh is popular in Ireland, but not recommended in the US.

Maeve

This spelling, which came to the attention of readers of the best-selling Angela's Ashes as the name of author Frank McCourt's father and brother, the latter of whom wrote a bestseller of his own, lends the biblical name a more expansive, almost boisterous image. Malachy is one of the <a href="https://nameberry.com/baby-names/168/irish-names">Irish baby names</a> that manages to strike the golden mean between familiarity and distinctiveness.

Malachy is also the anglicized version of Melaghlin, one of St. Patrick's first companions. It was borne by the High King Malachy, who defeated the Vikings at the Battle of Tara in 980. St. Malachy was a reformer who reorganized the church in Ireland after the Viking raids.

Another origin, via a somewhat circuitous route, is from the surname Mac Seachnaill, "son of Seachnall", the Irish form of Secundus.

Irish actor Cillian Murphy has a son named Malachy.

Malachy

Although it is now more often used for baby girls in Ireland, Naoise is originally a masculine name. 
It belonged to a handsome young warrior in Irish legend, lover of the tragic Deirdre, who killed
herself after Naoise was murdered by the jealous king Conchobhar.

Naoise

Niamh, derived from the Old Irish Niam, is an ancient Irish name that was originally a term for a goddess. In Irish myth, one who bore it was Niamh of the Golden Hair, daughter of the sea god, who falls in love with Finn's son Oisin and takes him to the Land of Promise, where they stayed for three hundred years. Niamh can be Anglicized as Neve, Nieve, or Neave.

Niamh is particularly popular choice in Northern Ireland, Ireland, Scotland and England and Wales. Niamh Cusack is part of the acting family that also includes Sinead (wife of Jeremy Irons), Sorcha and Padraig. Americans have recently become better acquainted with Niamh via the heroine of Christina Baker Kline's bestselling novel Orphan Train.
Here, the Anglicized Neve would undoubtedly prove simpler, if less intriguing. Actress Neve Campbell pronounces her name (a family name) "NEV", and Neve is the daughter of Conan O'Brien.

Niamh

The friendly and sporty feeling Nolan blends some of the best qualities of other popular boy names. With the gentle but energetic sounds of Noah, a hint of the classic Nicholas, and the cool, surname-style vibe of Greyson or Colton, it makes for a familiar and grounded choice. 
Popularized by the baseball player, Nolan Ryan, Nolan has been steadily climbing up the charts since the 1970s, and it entered the US Top 100 in 2011. While it has never been a Top 50 name, it is given to a substantial 5000 babies every year. 
Nolan is the Anglicized form of the Irish name Nuallán, meaning “noble and famous” or “champion.” 
This could give you the fun option of nickname Champ, while also providing the name with weight and history: the O’Nolans were once a chiefly Irish family, descended from the first Celts to settle in Ireland. 
A once very American feeling choice, Nolan is now more popular in France and Canada. It is on the rise in England and Wales too, a favorite in The Netherlands and Belgium, and at #22 in Hungary (albeit with the Hungarian spelling, Nolen). 
Notable Nolans include the fashion designer, Nolan Miller; the Modern Family actor, Nolan Gould; Marvel and DC voice actor, Nolan North; and the actor and singer Nolan Gerard Funk of Glee fame. Some may associate it with the Nolan Chart, a political spectrum diagram invented in the 60’s, while others may be more familiar with Nolan Chance, from the game Fortnite. 
Familiar and cool, grounded and approachable, Nolan continues to hold its steady place in the lower end of the US Top 100. 
Do you love Nolan but want some more inspiration? Other names inspired by Irish surnames include Nevan, Blaine, Riordan, Donnovan, and Callahan. For names that share a similar sound, Bowen, Milan, Noel, or Roland might appeal.

Nolan

Oisin is one of the most popular <a href="https://nameberry.com/baby-names/168/irish-names">Irish baby names</a> in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.
 Ossian is another version, reflected in the eighteenth century Ossianic poems of James Macpherson, which transformed him into a Scottish hero and also popularized the names Oscar, Fingal, Selma and Malvina.

Oisin

A calm and gentle multicultural choice. Oran is popular in Ireland, where its Gaelic form is Odhrán, meaning "little green one". In Scottish Gaelic, the name means "song", and in Hebrew, it's a combination of Or "light" + Ran "singing".

Oran

An Irish last-name-first-name that could make a child feel distinctive, while still having the regular guy nickname of Quinn. Christine Taylor and Ben Stiller spelled their son's name Quinlin. 

 Quinlan would make a fitting choice for a fifth baby, since quin in Latin signifies five.

Quinlan

Quinn is one of the first popular Irish unisex surnames, a strong and attractive choice on the rise for girls but still popular for boys. Quinn was used for about 3000 baby girls and 700 boys in the US last year.
 
Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning "descendent of Conn." Conn has two possible derivations—the Old Irish cond, meaning "intellect," or cenn, meaning "chief." One of the most notable Quinn clans was from County Tyrone in Northern Ireland. 
 Quinn started taking off for girls in the mid-nineties, possibly influenced by the popular show Dr. Quinn, Medicine Woman. Since then, there have been female Quinns on the animated MTV show Daria, on Zoey 101, and—most prominently—on Glee, featuring cute blond cheerleader character Quinn Fabray.
 Some other, more <a href="https://nameberry.com/lists/category/unusual-names">unusual names</a> with the Q-factor: Quincy, Quintina, Quintana, Quinta, Quilla--and, on a different note, Queenie.

Quinn

Has a legitimate first name history in its native land and an appealing meaning, but pronunciation is far from obvious. 

Riordan

Ronan is the compelling legendary name of twelve Irish and Scottish saints that is now drawing some deserved attention; this cousin of the ascending Roman and Rowan was chosen by actor Daniel Day-Lewis and his writer-director wife Rebecca Miller in 1998, and more recently by actress Catherine Bell.
 Ronan is a Harry Potter name—that of a centaur who lives in the Forbidden Forest. Ronan Keating is an Irish singer, Ronan Farrow is a TV personality and Hollywood scion, and its presence as a surname is represented by young actress Saoirse Ronan.

Ronan

Before the young Irish actress Saoirse Ronan made her mark in the films Ladybird and The Lovely Bones, few of us had heard this name, let alone known how to pronounce it. But now it is slowly way edging its way into the mainstream, particularly, of course, with parents who have Irish roots. It made its first appearance in the US Top 1000 in 2016, when it was the third-fastest-rising girls' name.
 
Saoirse originated as a baby name in 1920s Ireland as an applied use of saoirse, the Gaelic word for "freedom." The name was first adopted during the Irish War of Independence, when the Irish Republican Army fought the British Army for the liberation of Ireland from British rule. In modern times, Saoirse, as well as a host of other <a href="https://nameberry.com/list/1051/gaelic-names">Gaelic names</a>, are being revived in Ireland, the UK, and the US.
 Another related name Is Sorcha, pronounced SURK-ha and meaning "radiance": in the film Willow, the character's name is spelled Sorsha – another way to pronounce it.

Saoirse

Parents who have tired of Sean are now contemplating Seamus, the Irish form of James, which has a lot more substance and verve.
 One of the name's most famous bearers is the 1995 Nobel Prize-winning Irish poet Seamus Heaney. Seamus is also a Harry Potter name—Seamus Finnigan is a half-blood wizard friend of Harry's.
 At a time when the police force was predominantly Irish, "shamus" became a slang term for a detective.

Seamus

Sean, after a long reign as one of the top <a href="https://nameberry.com/list/328/irish-baby-names-for-boys">Irish boys' names</a> in the US, has now slipped as parents look to fresher Irish choices such as Liam and Aidan. In Ireland, Sean is still highly popular, but variation Senan, an Anglicized spelling of diminutive Seanan, is also stylish in Ireland. While Sean is the Irish form of John, Seanan and Senan may be thought of either as Sean diminutives or relatives of the Latin word "senator".

Sean

More streamlined – and more authentic – than Shawna.

Seana

St. Senan was a famed founder of monasteries, whose ruins can still be seen. Legend has it that before he could found it, he had to banish a great monster.  Other versions are Sionan, Sinan, Synan and Sinon. Seanan is also a pet form of Sean.

Senan

Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.
 
Siobhan is a lovely Irish name which has spawned many Anglicized variations, but using the original form preserves the integrity of one of the most beautiful <a href="https://nameberry.com/baby-names/509/irish-names-for-girls">Irish girls' names</a>.
 
There have been a wide variety of fictional Siobhans, from a Detective Sergeant in the John Rebus novels to a vampire in Stephenie Meyers's Breaking Dawn to a character in J. K. Rowling's The Casual Vacancy. Most famous these days is the only daughter Siobhan in TV's Succession, appropriately nicknamed Shiv.

Siobhan

A relatively modern (18th C) Irish Gaelic name, Siofra or, more properly, Síofra with the fada has its roots in superstition. In the past, when babies were born in Ireland their families feared that the fairies would steal the baby and leave an elven changeling child in its place. It’s an uncommon name starting to pick up in its native country.

Siofra

Less popular than the Bueller-inspired Sloane but following on its coattails, this name ranks toward the middle of the Top 1000, but we see both spellings sticking around for years to come.

Sloan

Sloane is a sleek, sophisticated surname name that has gradually morphed over to the girls' side. With its distinctive and intriguing sound, Sloane has been in the US Top 1000 since 2009, and in 2022, it made its first appearance in the UK charts, jumping more than 400 places in a single year.
 
Derived from the Irish surname Ó Sluaghadháin, meaning "raider" or "mobilizer", Sloane shares that preppy feel of Blair, Delaney, Ellis, and Quincy. 
 Sloane has been the name of girlfriend characters in Ferris Bueller's Day Off and Entourage, and was used for a character played by Olivia Munn on The Newsroom. The video game, Overwatch 2 includes a character called Sloane, English actor Barry Sloane has made it familiar through his surname, while Sloane Stephens is a highly ranked tennis player. 
 Comedian Rob Coddry called his daughter Sloane Sullivan, while rapper Macklemore gave his daughter the name Sloane Ava Simone - and let her direct one of his music videos in 2023. 
 The association with London's Sloane Square and the upscale clique of Sloane Rangers, who have included Princesses Di and Kate, gives it some extra panache.

Sloane

A popular Irish name virtually unknown here, but one that feels like it could follow in the footsteps of Siobhan and Saoirse. It's pronounced SOR-ka, but with a little hiccup between the 'r' and the 'c' that's difficult for non-Gaelic speakers to reproduce. Spelled (and pronounced) Sorsha, she is a major character in the movie Willow.

Sorcha

Though it has a Scandinavian ring, this is an out-of-the-ordinary Irish family name. The hard 'T' at the beginning prevents it from sounding as feminine as, say, Loren. Torin's Passage was an early video game.

Torin

Troy shot to popularity as a first name in tandem with that of 1960s heartthrob Troy (born Merle) Donahue; its image has now, thanks in part to the Brad Pitt-starring epic, Troy, receded back to conjuring up the ancient site of the Trojan wars.

Troy
