Oh dear, I don't think I could re-name everyone. So many of them just fit with the names they already have.
I do have to admit that I've always had a little problem with bellas name.
I like it when people have unique names or names that you don't hear all the time. I might have gone with something celtic but still mainstream.
As for Edward...I love his name, it fits him but if I HAD to change it I would probably pick Alexander or something regal sounding. I dunno. It's funny because I like Edward on him but otherwise i'm not a fan of the name. *shrug*
