Who was Caine’s wife?

Apparently it’s a split between Zillah and Enneia, though there are other mentions that Enneia was a child of Lilith (which, while not mutually exclusive with being Caine’s wife, is very weird because Caine also had a love affair with Lilith)

I'm kinda split personally because while I don’t think Caine would just leave the city without the girl he loved so much to blood bound her with him (since apparently the murder of 2nd generation was with him outside the city) I don’t see why he would want to marry the daughter of his lover, or why he would leave someone else to embrace her instead of himself
