I don't know that I've seen it before, or at least it didn't pop out at me. It has a magical vibe I'm into, the same sort of vibe as a lot of my favorites like
Ourania,
Artemisia,
Lyra, Zephyra,
Theodosia, etc Flowery but unusual, you know.
I think most all your combos are quite nice but I like best:
Crescentia AvelineCrescentia Caterina /
CatharinaCrescentia Corisande
Crescentia CorneliaCrescentia CosimaCrescentia IantheCrescentia Iseult /
IsoldeCrescentia JocastaCrescentia MelisandeCrescentia MelusineCrescentia OdileCrescentia OpalCrescentia OpheliaCrescentia Raphaela - I especially love this. Sounds like the name of a renaissance lady, a lover of Casanova or something
Crescentia VerenaCrescentia Viviana
