I don't know any of the answers to your questions but can add Metis would not have a last name such as the white man's name, smith or Jones so they would add a last name that they liked or even be given one from what I understand, So the last names may not all be the same but they could be related. I to am looking up what could be (I am sure it is) Matis in my family history and it is hard to find. There is a web page under Metis Families Red River Settlement MB. That gives information I hope this helps...can you tell me where did you get the book by Gail Mourin on the Manitoba Scrip? I would be interested in knowing if Alexander Ferguson and Jane Jones are in the book as I am looking for the parents of Jane Jones I have seen it on the internet but wonder if it is in stores. Good luck. Toni
