I met a women who I gathered was First Nations (or something like that). I struggled to ask the question to elicit the response to find more about her heritage and culture. What is the word that distinguishes between different North American aboriginal people? I've heard them called "nations" but it would be ambiguous to ask "what Nation are you from?" because the "official" one would be Canada.
For example would it be politically correct to ask "What type of First Nations are you?" or "Are you part of a certain band?". I was looking for an answer like "Cree" or "Salish".
