I just found the most perfect native american name for a skyrim character I'm going to try It's an Algonquian name meaning shouts. Though this name is probaly best for a character who's doing the main quest focusing on shouts. I haven't finished the list I'm going to keep on looking for skyrim related native american names.
Some info I found "The Algonquins are original natives of southern Quebec and eastern Ontario, in Canada. Today they live in nine communities in Quebec and one in Ontario.
I don't think any one race has just one culture in it the races that seem to have a native american feel to them would be the dark elves in the ash mountain and the wood elves of valenwood. But I might use a light skined redguard. Or a dark skined nord. Love your avatar by the way!
