bellerose had a lot of good ones, so I'll just add:
Veda (and who didn't love this name after watching the 'My Girl')?
Vienna (not the worst place name ever)
Valkyrie (personal favorite)
Valen (I know a girl named this...so lovely!)
Vita / Viva
Virgil (I totally think this one could be unisex)
Vern (Knew a girl named this in college who was very, very awesome)
Viola (favorite character in Twelfth night and a lovely instrument)
Um, yeah..i LOVE 'V' names
I was thinking of the name Maven today, so that could be an option.
