Girl names escape me.?

My husband and I have already decided that our first son will be named Anthony Tobias and we will call him Toby because they would share a first name. But i cannot think of a girl's name in contrast. He likes Alexandria, but I KNOW he got it from a sexy girl he knows. i dont want that reminder on my daughter. this is only an issue now because we found out we're having twins, a boy and a girl, and while Toby is decided, i can't settle on a girl's name.
