The Merchant Princes series by Charles Stross posits a parallel world where North America was settled by Vikings. What are the gods of their religion that are mentioned? (It seems they are used mostly for swearing...) I have these four so far: Sky Father, Lightning Child, Crone Wife, Trickster Cousin - what are the others?
Now I found also Sky Lady and Sister Corn, I think. (But who they are could also be interesting.)
