Andrew Hussie's MS Paint Adventure webcomic Homestuck has a character 'Kanaya', derived from the name 'Kanya'. However in the character's case, it is from the Sanskrit Kanya.
I think Kanya is a rather pretty name, and I like the way it sounds (if my idea that it rhymes with "Tanya" is correct). However, it strikes me as sounding very much like a Russian nickname. (Not that this is a bad thing. I like the sound of Russian nicknames. I just find it unusual that a non-Russian name sounds so much like one.)
