Whatever you name the baby, make sure you're happy with it and not be pressured by anyone to name her something you don't like.
I think the person will outlive the popularity of the book. I've always thought Esme was a pretty name, too bad it got too popular from Twilight. Have you considered Eliza Alise?
I had the name Esmè picked out for a girl too and my Husband said no as it was too much like a Twilight name. We're having a boy though so it is now irrelevant
