Well, like I said, we're playing fast-and-loose with canon, so the exact specifics of lore and history really aren't all that important.  What matters is that it's recognizable as the character; you can mix-and-match stuff to your heart's content as long as people can look at the end result and go "okay, yeah, that's Thor."

This is generally my rule of thumb anyway for playing superhero characters, given there's so much conflicting history and retcons to deal with. I try to make an amalgam of everything, I.E with Spider-Man, he's about the age that he is in the modern comics, but was bitten by a genetically altered spider as he was in the Ultimate Universe and is engaged to MJ for the first time - as opposed to having been married to her only to sell that off to the literal devil. 

If I were to write out his full history, it'd probably be some elaborate combination of 616, Ultimate, MCU, the Raimi films, the Spectacular cartoon and any other version I love. It makes things more fun and covers alot of bases, while never messing with the 'classic' formula of who these characters are.
