I have an Evie here (officially Evelyn). Was not the popular, until the year I used it and suddenly it is top 10 in our area (and I swore never to have a top 10 name). Now DD2 has 2 other Evie's in her room at Childcare, one even has the same initial for their lastname, so very thankful her fullname is Evelyn. I spoke to the one of the other Evie mum and she was like me, thought she was picking an unpopular name.

So as much as I love the name, I would say avoid it if you don't want popular, or at least have it as the nickname.

Good luck!
