Popular in Ireland

This member of the aden/ayden extended family is a popular choice not only in the US but across the pond in England, Wales and Scotland as well. Angie Everhart has a son named Kayden Bobby.

Currently overshadowed by the bright and lively Leo, Leon feels a slightly more serious, more quietly confident than its short and trending counterpart.

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.

Millie is back. It's a Top 100 name throughout much of the English-speaking world, though not yet in the US. Millicent would be an appealing long form, but many people are using Millie all by its cute self -- so many, in fact, that it returned to the Top 500 in 2015 for the first time since World War 2 and continues to climb.

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.

Oisin is one of the most popular Irish baby names 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.

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.

This spirited Gaelic classic, which became popular in Ireland via the illustrious twelfth century king Rory O'Connor, makes a highly energetic choice, now used for either sex. Rory's gender split is still trending boyward; it's one of the coolest boys' names starting with R.

The origin of the Anglicized Ryan, this Irish name feels like a brighter and fresher alternative.

An authentic choice for your little Irish Rose, chosen by singer Sinead O'Connor for her daughter.

Sadhbh was the name of several real and legendary Irish princesses, including the daughters of Conn of the Hundred Battles, of Queen Medb of Connacht, and of King Brian Boru. It's also written Sabha. One of the most authentic Irish names for girls, it is also unfortunately one of the most difficult to export.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

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.

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.

Shay has an old-fashioned feel due to its association with the word for a kind of horse-drawn carriage and at the same time seems modern thanks to its simple straightforwardness. Use Shay as a phonetic equivalent of the Irish surname Shea or the Hebrew male name Shai, or as an abbreviated form of such names as Seamus or Shane.

Sonny is one of the generic boy nickname names making a surprise reappearance, and it was recently used by actor Jason Lee. Another surprise: It's been on the US Top 1000 list every year since 1927, reaching a peak in 1975, when it hit Number 428.

The name of several ancient kings and princes of Ireland, Tadhg became so common at one point that it was used to represent a kind of Irish Gaelic everyman, or man in the street, as Paddy and Mick would later. Tadhg has seen a major resurgence in recent years and is also now ranked in England. It is sometimes used as the Irish equivalent of Timothy and is also anglicized as Teague and Thaddeus. Tadleigh and Thad are pet forms. Pronunciation is like tide ending with a g.
