I would like to echo the others who brought up Ragnarok (and all Norse myth, just generally, definitely for names anyway)... Read it enough and with the right eyes and you'll start to think everything in aSoIaF references it! For the uninitiated check the Wikipedia entry here and pick out the familiars. I am definitely reading too much into it though. You start to use the myths to predict what will happen in the books, and then you start to go crazy. :bang:
