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.

Sullivan is a jaunty Celtic three-syllable name, with a real twinkle in its eye. It was immortalized in the 1930s classic film Sullivan's Travels and was chosen for one of Patrick Dempsey's twin boys. Nickname Sully is equally jaunty.

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.

Shane ambled into the picture via the 1953 movie, adding a cowboy twist to its Irish essence. A variation of Sean with a hint of Shay and Zane, it is a popular choice in Ireland.

The short but solid Irish surname Shea works well for both genders thanks to its soft, succinct sound. The traditional Irish form is Séaghdha, though it could also be used as a short form of Séamus, connected to James.

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.

Sean, after a long reign as one of the top Irish boys' names 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".

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.

Parents who have tired of Sean are now contemplating Seamus, the Irish form of James, which has a lot more substance and verve.

Gentle yet rugged, cool but well established, Shay is straightforward and memorable. An anglicized spelling of the Irish Shea ("dauntless, fine, good" "hawk") and the Hebrew Shai ("gift"), Shay appeared in the Top 100 in Ireland and the Top 400 in England and Wales in a recent year.

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.

A variant spelling of either Irish Shea or Hebrew Shai, Shay feels at once vintage and modern.

Shawn is a phonetic spelling of Sean that may be past its peak – it was a Top 30 name in the early 1970s – but is still quite popular for boys: over 500 baby boys were named Shawn in the US in the most recent year counted vs 800 given the original Sean spelling.

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.

Shaun is the least popular spelling of the once-wildly popular name, more usually spelled Sean or Shawn. Parents who have a reason to choose this name now would (and should) most likely go with the original Sean. Alternate spelling Shawn is four times more popular.
Shaun (and Shawn) were considered the feminized spelling of the name back when it was becoming a unisex name in the early 1970s. In all spellings, Sean has become once again decidedly masculine.

Not to be confused with shea butter, this name is a common surname in Ireland, combining spirit, substance, and gentleness. The traditional Irish form is Séaghdha (SHEH), though it could also be used as a short form of Séamus, connecting it to James.

The name of the longest river in the British Isles rose to the US Top 25 for girls in the 1970s and the Top 100 for boys, but has fallen off the Top 1000 for both genders. At the latest count, the name Shannon was given to about 200 babies in the US, about a third of those boys. As a favorite Irish name, Shannon has now been supplanted by newcomers such as Saoirse and Seanan.

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.

Sheila peaked in popularity from the 1930s to the 1960s (she reached Number 49 in 1965), along with Maureen and Colleen; parents today would probably go back to the original Cecilia or forward to Shea.

Upper crust-y surname Sheridan gains some energy when used for a girl.
