Isla

Pronounced EYE-la, this girls' name references Isla, a river in Scotland, as well as Islay, a Scottish island. It’s a super-popular name in Scotland and in other English-speaking countries like England, Australia, New Zealand and Canada. But only in the last 10 years has the name become a hit in the US. Maybe it was because of the box office success of “Wedding Crashers,” a 2005 comedy featuring actress Isla Fisher, that made people notice her pretty name.
