Baby Girl Name

Hi! we cannot decide on a name for our newest addition, a little girl coming in March. Right now we like Evie Layne. Our last name begins with O. I think it flows and sounds so sweet. We already have a Jack David and an Emma Grace. Evie is a bit more unique and non-traditional. Does it go with the others? I realize everyone has a different opinion but please be nice if you comment.

Thanks so much!
