Thing about
Bella and
Edward though is that many people recognize
Edward as a standard name and many would at least consider it anyway and
Isabella was already popular before the book and movie came out, so this just kinda adds to the hype of potentially pushing some people either towards or away from those names.
Rosalie, however, is rare enough that for some people, that's prob'ly the first place they've ever heard it, so it may spark some to consider it and leave others thinking it's just an obvious movie name 'cause they've never encountered a
Rosalie in real life.
