Aoife, pronounced EE-fa, is derived from the Irish word aoibh, meaning "beauty." Aoife was borne by several different heroines of ancient Irish legend. In one tale, she was the fiercest woman warrior in the world and enemy of her twin sister, Scathach.
 
Aoife is very popular in Ireland, and is catching on across the UK as well. Aoife is sometimes Anglicized as Eva, but the names are from independent origins. Eva shares roots with Eabha and Aoibhe, both also currently popular in Ireland.

Brigid is the simpler Irish version of the name of the goddess of fire, which may also be spelled Brighid. Other variations include Bridget, the most usual spelling in the U.S., and the French Brigitte.
 The most famous female saint of Ireland is the fifth century Brigid, who was abbess of Kildare and is the patron saint of scholars. Because of her sanctity, her name did not come into common use in Ireland until the eighteenth century, after which it became wildly popular, eventually used as a generic name for an Irishwoman.
 According to Irish myth, there were three sister goddesses named Brigid: the goddess of poetry, the goddess of healing, and the goddess of agriculture.
 The ancient Brigid may not be exactly stylish but it's beautiful and strong, a true Irish classic.
 Nicknames include Bridie, Bidelia, Biddy, and Breda.
 In literature (and film), Brigid is the devious character in The Maltese Falcon.

Brigid

Caoimhe, pronounced (more properly) kwee-va or kee-va, is a pretty and distinctive Gaelic name but one that could well lead to no end of confusion outside the Irish community. Even in its native habitat, it is sometimes spelled Keeva.
 Caoimhe comes from a word with several positive meanings--beautiful, precious, beloved, gentle, and graceful. It's also the name of an Irish saint.
 Caoihme has been very popular in Ireland in recent years.

This Katherine variation, used through Ireland and Scotland, is pronounced like Katrina. The name became popular after the Crusaders brought home stories about the colorful fourth century martyr, Catherine of Alexandria. Its later popularity increased following the success of Robert Louis Stevenson's 1893 Catriona, the sequel to Kidnapped.

Catriona

Extremely popular in Ireland, Ciaran is also well used in England and is beginning to be adopted by parents in the U.S., though usually via the more American-friendly Kieran spelling. The Irish spelling is, however, becoming more familiar on this side of the Atlantic, due to the rising popularity of Belfast-born actor Ciaran Hinds.
 Although it was the name of twenty-six saints in Ireland, Ciaran was not used as a secular name there until the 1950s.

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.
 There are several Saint Cillians, including one who was sent to Bavaria to convert the natives and was martyred for his trouble. 
 Patrick Woulfe, a Catholic priest who was instrumental in reviving native Irish names in that country after the war for independence from England in the 1920s, theorized that Cillian might also be related to a Gaelic name meaning war.

Cillian

This Irish surname-name certainly feels brighter and fresher than the English equivalent, Clark.

Cleary

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.

Eamon is one of the traditional <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> that has not yet emigrated to the US. This Irish name pronounced ay-mon was popularized by early president of the independent republic Eamon de Valera (birth name George), who was born in the United States to an Irish mother and a Cuban father. Eamon definitely has possibilities as a successor to the epidemically popular Aidan/Aiden.
 Though it may be an older generation name in Ireland, it would sound fresh elsewhere.
 The original spelling of the name is Eamonn.

Eamon

Pretty and soulful name of a goddess from Irish mythology and several Irish saints. Singer Enya, born Eithne Ní Bhraonáin, has made the Anglicized spelling familiar. Eithne comes from the vocabulary word "kernel", which was used as a term of praise in old bardic poetry.

In Celtic lore, Fergus was the ideal of manly courage, making it a charming, slightly quirky Scottish and Irish favorite.
 As a name, Fergus forms a link between Ireland and Scotland, as Gaelic tradition has it that Irish Prince Fergus Mac Eirc and his two brothers crossed the sea and founded the kingdom of Argyll in Scotland, thereby making this an excellent choice for parents of either country or those of combined heritage.
 Fergus has often popped up in children's literature, such as in Thomas the Tank Engine and Friends, and is the name of one of Shrek and Fiona's triplets. On a loftier level, there is the Yeats poem, Who Goes With Fergus? and Fergus MacIvor is a central character in Walter Scott's novel Waverley.
 With the nickname Fergie having been appropriated by two high-profile females, Gus might make a more approachable option these days.

Fergus

If you like the Finn names and love James Joyce, Finnegan is extremely winning. Will & Grace 's Eric McCormack chose the Finnigan spelling for his son. And of course Finnegan gains you access to the great short form Finn.
 James Joyce took the title of Finnegans Wake from an old Irish-American song.
 Finnegan represents a whole genre of Irish family names you might consider, such as Harrigan, Brannigan, Corrigan, Donegan, Mulligan, Flanagan and Lanigan.

Finnegan

Fiona entered the American consciousness with the opening of the 1954 Broadway musical Brigadoon, but didn't come onto the U.S. popularity list until 1990.
 
Fiona is the best known of a group of related Gaelic names, which is ironic because it's the only one without genuine traditional roots — it was found first in James Macpherson's Ossianic poems and then popularized in the late nineteenth century as a feminine pseudonym for William Sharp, a Scottish male writer. <a href="https://twitter.com/HJosephineGiles/status/1555216419721297922">Some researchers believe</a> that Fiona Macleod was Sharp's identity as a trans woman.
 
Its recent spike in popularity owes much to singer Fiona Apple and also possibly to Princess Fiona in Shrek. In fact, there have been numerous Fionas on the big and small screens, from The Thorn Birds to Josie and the Pussycats, Four Weddings and a Funeral to Nurse Jackie to Shameless.
 
Jennie Garth and Chad Lowe have daughters named Fiona. It's also Julia Roberts' middle name.
 
If you're looking for something more authentic, consider Fionnuala.

Lochlan and Lachlan are running neck and neck and both rising into the Top 1000. Which spelling you use is purely a matter of taste.

Lochlan

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

Maebh

An Old Testament name with a Gaelic lilt, Malachi entered the list in 1987.
 In the Bible, Malachi (pronounced with the final syllable as EYE), was the last of the twelve Hebrew prophets, who foretold the coming of Christ. 
 In Anthony Trollope's Phineas Finn, Malachi is the name of the hero's father, and in James Joyce's Ulysses, Malachi Mulligan is a medical student. The lighter-hearted Irish version is usually spelled Malachy.

Malachi

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

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.

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.
