I can't make up my mind!

So, for the past four weeks, I had decided that I wanted to name my upcoming little girl, Ava Isabella. Now, I know everyone is going to say "ava is so overused, etc", but I live in a very, very small town, and I don't know of a single Ava here. However, I've recently also fell in love with two other names. Evangeline and Adeline. *Squinches eyes shut* I already told everyone I was going to name her Ava, but now I can't decide!! I really like all three of these names. I'm also having trouble with the middle name. I want to name her Isabelle or Isabella (thats the only stipulation that the father had..he wanted her named after his grandmother if possible...) Which sounds better? I need your help girls! Else, I'll go nuts trying to decide what to name her. Would it be considered bad taste to change what I was going to name her, or should it not really matter, since its my baby? What combination would you use with the names provided? Help!
