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.

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.

One of the first of the appealing Irish surnames to take off in this country, this boys’ name has long outgrown its "Mellow Yellow" association, which came via the single from a sixties singer-songwriter named Donovan.

No, the pronunciation--ro-SHEEN--isn't immediately obvious to the non-Gaelic viewer, but the sound of this shiny Irish version of Rose is pretty enough to make it worth considering. Very popular in its native Ireland, it's one of many Irish girl names finding a wider audience. Earlier generations Anglicized at as Rosaleen, but we stay stick to the original.

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.

Ferelith is an unusual yet deeply-rooted Scottish girl's name, also found in ancient Ireland and drawn from the Gaelic Forbhlaith or Forbflaith. While it went through a period of dormancy after the Middle Ages, there are some modern women named Ferelith, including actress Ferelith Young and Princess of Denmark Anne Ferelith Fenella Bowes-Lyon.

Somhairle is a rare masculine name with deep Gaelic roots, predominantly found in Scottish and Irish traditions. Pronounced roughly as 'SOR-la' or 'SORE-luh,' it represents the Gaelic form of the Norse name 'Sorley' or 'Somerled,' derived from 'sumarlidi' meaning 'summer traveler' or 'summer warrior.' The name carries historical significance, notably associated with Somhairle MacGillebride, a 12th-century Norse-Gaelic warlord who established the Lordship of the Isles in Scotland. Despite its rich heritage, Somhairle remains exceedingly uncommon outside Gaelic-speaking regions, largely due to its challenging pronunciation for non-Gaelic speakers. The name embodies Celtic cultural pride and connection to ancient traditions. For parents with Scottish or Irish heritage seeking an authentic cultural name with historical depth, Somhairle offers a powerful choice that honors ancestral roots while standing distinctively apart from more common Celtic names.

Cael is the name of the angel of the zodiac sign of Cancer and also of a warrior of Irish mythology. Its ascendance to the Top 1000 over the past decade probably has to do with its similarity to Cale and Kale (and Kyle and Cayden etcetera).

Ailbhe is a unisex Irish name that has appeared throughout Irish history, borne by a 6th-century (male) saint, and by a female warrior of Fianna, a legendary group of women warriors, led by Fionn MacCumhaill. Today, the name is predominantly used for girls, likely because it sounds similar to Alma, Ava, and Alba.

One of the best known of the Irish girls' names, thanks to singer Sinead O'Connor. Though it's still in the Irish Top 100, it's no longer quite as fashionable in Ireland as Aoife or Aisling. But by now everyone in the Western World knows it's pronounced shin-aid and so would have no trouble fitting in on an American playground.

The name of the son of the legendary Finn McCool is often Anglicized to Ossian, but the original has recently been revived in Ireland and is currently among the most popular boys' names there.

Fionn, the modern Irish form of Finn, is more popular in Ireland these days than Finn, which is rising fast in the U.S. where Fionn is virtually unknown. That's probably a good thing, because few Americans would know that Fionn and Finn have the same root and are pronounced the same, like the fin of a fish. It's the namesake of a great hero from Irish mythology, Fionn MacCumhaill, who acquired divine wisdom by eating an enchanted salmon of knowledge.

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 Irish names for girls, but Americans will definitely have pronunciation issues.

One of many Irish names that, despite pronunciation challenge, are beginning to be taken into consideration here as authentic Celtic versions of familiar English names.

Pronounced like Owen, this was the name of several early Irish kings and saints, as well as a celebrated Ulster hero. Often spelled with two 'n's in Scotland, it has been Anglicized as Ewan, Ewen, Euan, Owen, Hugh, or Eugene.

Ruadhan (sometimes spelt with a fada: Ruadhán) is a fashionable name in its native Ireland. Borne one of the Twelve Irish Apostles, it originated as a diminutive of Ruadh, meaning "red-haired". It has sometimes been Anglicized as Rowan.

In early, pre-Norman Ireland, this name was borne by both a sister and a niece of high king Brian Boru. Now, the English form Orla is more commonly used.

This lovely Gaelic name, very popular in the Emerald Isle, has inspired a whole host of diminutives (including Nuala and Nola) and variant spellings, from Finola to Finula to the Scottish and English Fenella. In Irish legend Fionnuala was one of the four children of Lir who were transformed into swans for 900 years.

Guthrie, one of the most attractive Scottish names that's also a surname, has a particularly romantic, windswept aura, with a touch of the buckaroo thrown in.

Popular in Ireland, though not as popular as its spelling variant Eimear, Emer is a mythological name, associated with the legendary wife of the warrior hero Cuchulainn. She was said to possess the six gifts of womanhood: beauty, voice, speech, wisdom, chastity, and needlework.
