Rosabelle?

[Kghl03]

Pretty or trying too hard to be traditional but different?
Would personally shorten to Belle not Rosa as MIL name is Rose (love her to bits) so not worried about it being similar.

Too twee for me.

I don't like Belle or names ending with it. Rosabel is better but I do prefer Rosalie.
