Great list! :)
I like:
CarolinaAriadna (I prefer
Ariadne, though, with nn
Aria)
Sunniva (Loving this right now, its on my top ten, too)
Eva (I personally prefer
Eve and I think
Eva makes a very good nn for
Sunniva, too)
ThaliaMarina and
Valentina (I actually knew an Italian girl named
Marina Valentina and even her surname was great, too. I loved the sort of rhymey-ness about her name)
