To me,
Viola is quite a cute name. It makes me think to the eponymous colour, flower and instrument (in Italian "viola" has these four meanings). I also really like the variants
Violette and
Violante (maybe more than
Viola).
Here are some great combos:
Viola Maria or
Maria ViolaViola HopeViola HermioneViola RoyseViola MayViola Meg or
Viola MeganMarie ViolaViola HenrietteViola Annette
