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.

A quaint and quirky flower name, until recently considered a bit too prim for most American classrooms but brought back to life in recent years by the attractive character of Primrose "Prim" Everdeen in the Hunger Games series. In the Top 300 girl names in England and Wales and on Nameberry, Primrose remains rare in the US, but is made more accessible by a raft of sweet nickname options, including Rosie and Posy.

Unspecific place name with a wonderfully wide-open, spacious, western feel; used for a character in Thomas Pynchon's novel Vineland.

Ida is one of those terminally old-fashioned names that suddenly sounds fresh again, especially given how fashionable it is in Europe. Ida, usually pronounced ee-da, is a Top 100 name in Scandinavia and German-speaking countries, and is rising more gently in the US.
