In the land of the nickname name, otherwise known as the UK, where diminutives like Freddie, Millie, Maisie, Alfie and Ollie are all the rage, Evie has been in and around the Top 10 for several years now (currently #15). In the US, she entered the popularity ranks in 2007 for the first time since 1941, appreciated for its energy and spunk. I
Natalie Portman played an Evie in V for Vendetta and Rachel Weiss bore it in The Mummy.
Evie, of course, can also be used as a nickname for Eve, Eva, Evelyn, Evangeline, etc.
