Haha, "Kali" is MY name, lol! And while it is the name of a Hindu goddess, it is also Greek. My father is Greek and my name is a derivative of Kaliopea and it means "flower" or "beauty" in the greek language.

How about....
Isis (Egyptian goddess of nature, fertility, and beauty)
Annis (also of greek origin and means "pure" or "satisfaction")
Pania (refers to the Earth)
Matilda (just a fun name that sounds very "snakelike" and elegant)

Hope this is helpful!
