Irish Names

Fiadh is the fastest-rising girls name in Ireland, derived from the ancient root word for "wild". Sassy but gentle at the same time, it also entered the England and Wales Top 1000 in 2020 and has been steadily rising ever since. 
 The Anglicized form Fia is also on the rise in the UK and it could be one we might see rising in the US as well, thanks to its similarity to popular Mia, Thea, and Sofia.
 
Social media star Emily Clarkson named her daughter Xanthe Fiadh in 2024.

Rogan makes a great, roguish alternative for the more popular Logan, Ronan and Rowan.


Rogan

Well-established Irish and Scottish name that has never really caught on across the pond. Remembered by an older generation as the beautiful red-haired ballerina in the film The Red Shoes, Moira Shearer.

Moira

A name that Yanks might see as overly British, but combined with the right surname, it does have a measure of Sherlock Holmesian dash via Nigel Bruce, who played the original Dr. Watson to Basil Rathbone's Sherlock Holmes. 

Nigel

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/804/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.

Adair has flair, the grace of a Fred Astaire, and a daring, spirited vibe. It's usually considered a Scottish surname, derived from the name Edgar, though other possibilities are that it derives from the place name, Adare, meaning "ford of oak trees" or from the Irish Darragh meaning "oak tree". In any of these cases, it is pronounced uh-DEHR.
 
Alternatively, it may be used as a Portuguese name, likely as a twist on Ademar. Pronounced with three syllables ("a-du-EER"), it would mean "wealth and fame". 
 
A unisex choice, Adair does lean masculine, with 59 boys and 22 girls given the name in the US in a recent year.

Adair

Used far more for boys with this spelling, but still has a nice impish Irish feel for a girl. 

Devin

Spelling variation more popular in Germany than the original, which is also well-used there.

Fynn

The name of a historic Irish leader, Gannon has a solid, yet spirited feel. It was one of the fastest-rising names of 2014, but that trend didn't continue. One pop culture influence was the name of Teen Mom 3 son Gannon Dewayne McKee.

Gannon

Kim Basinger and Alec Baldwin put Ireland on the map when they chose it as a first for their daughter, saying that geographic names were a family tradition. And it seems they were a bit ahead of the curve (or trendsetting)—Ireland has been among the fastest-rising names of recent years. Other Irish place names include Shannon, Kerry, Galway, and Dublin.

Ireland

A few decades back, this name -- which hardly shows its Irish roots -- evoked a man in a gray flannel suit; now, though still upscale, it's more likely to be attached to a female. 

Sloan

More traditional spelling Murphy is far more popular, given to 783 girls (and 341 boys) in a recent year in the US — but this alternative is beginning to gain more attention. Given to around 80 girls in 2025 — compared to just 6 in 2015 when it made its US debut — it has yet to appear in the stats for boys.
 
Derived from the Irish Murchadh, it has the charming meaning of "sea warrior" — a big draw for fans of coastal names and those who value marine conservation.

Murphie

Like somewhat more popular twin sister Reagan, this vibrant last-name-first Irish choice makes a strong, straightforward option. 
 She does have a couple of downsides though. Regan entered the girls' list in 1974 – one year after the horror flick The Exorcist featured the demonically possessed Regan MacNeill. And before that, Regan was one of the faithless daughters in Shakespeare's King Lear.
 But putting all that aside – and you can – Regan makes a worthy successor to the overused Welsh Megan.

Regan

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

Irish place-name -- it's a river, a town, and an airport -- once popular but now supplanted by such newer immigrants as Saoirse and Seanan. 

Shannon

Made famous by F. Scott Fitzgerald and John Fitzgerald Kennedy; still works best as a middle name.

Fitzgerald

Stylish and boyish but could work for a girl -- especially one with brown eyes -- and Sully is a quirky and jaunty nickname.

Sullivan

Keelan is the Anglicized, phonetic form of the more traditionally-spelled Caelan, also in use.  While this name is said by many sources to be unisex, in practice in modern Ireland it is only given to boys.  An interesting, accessible choice largely unknown in the US.

Keelan

An Irish county name almost exclusively used for girls now. Kerrigan would be a more modern and masculine choice. 

Kerry

Arlo, an unexpectedly popular name for boys these days, is also finding new life as a girls' name. Its roots are primarily as an Irish or English surname, but it might also be a short form of the Spanish Carlos or Italian Carlo, forms of Charles.
 
The first name Arlo may be derived from the surname Arlow or the place name Aherlow, meaning "between two highlands". As a surname, it also has roots in a place name meaning "rocky hill".

 Arlo is a name with several unexpected lives thanks to celebrity associations. It was first known as the name of folksinger Arlo Guthrie, son of Woody; then it was revived by television's "Justified" character Arlo Givens. Now it's been spun again as a girl's name first by actor Johnny Knoxville and then by celebrity couple Leighton Meester and Adam Brody, who chose it for their daughters, no doubt inspired by soundalike girl names like Harlow and Marlowe.

 Arlo Parks (born Anaïs Oluwatoyin Estelle Marinho) is an up-and-coming British singer-songwriter, winner of the Brit Award for best new artist and the Mercury Prize for album of the year in 2021. 

 A growing number of girls are named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this cool retro name more into sleek surname territory.
