Isla is the name of a Scottish river, an island (spelled Islay), and the hot young red-haired actress Isla Fisher, wife of Sacha Baron Cohen. Isla is also among the fastest rising names in the U.S, and has been on the Nameberry Top 1000 for girls for the past five years! Surprisingly, it popped up a few times at the turn of the last century. Isla is currently in the Top 10 in England and in her native Scotland.
Isla Black Hitchens is a Harry Potter character.
Is Isla's newborn popularity a plus or a minus? Only you can decide, though the parent who chooses Isla because they've never heard it before and believes they rarely will again is sure to be disappointed.
Isla is part of a trend for simple, old-fashioned girls' names that start and end with a vowel: Ava, Ada, Ella, Emma, Eva, Ida, Ivy. Some other similar names that are not as trendy as Isla: Islay and Ailsa.
