urd, belldandy and skuld have the same father (it's highly thought it's kami-sama himself but i don't rekon seeing it said clearly anywhere in the manga, the OVAs or the movie) however they don't have the same mother. urd's mother is hilde as we all know, but belldandy and skuld's mother is a goddess, i don't believe her identity is revealed anywhere, else i missed something. :)
