Thanks everyone .. the context of the talk being given (Title: Geronimo didn't build casinos: The American Indian in Myth and Reality) is about representations of them in films (notoriously "DWW") making them footnotes to Frontier history and how "we" want them to be, rather than how they actually were or are ..

So, as an all embracing name I guess "American Indians" ..(qualified as indigenous peoples) ... just wanted to get it as near correct as poss (if not (clumsily?) politically correct **g**)
Interesting discussion though, it's turned out to be!
