Feel free to call yourself whatever you want but it's fact that the Jesuit order used the Metis to extend missionary work as far west as possible.
and it's a fact that the Hudson Bay Company used the Metis as guides and traders to further their expansion. They then ceded tracks of company owned lands to said Metis for compensation which ended up being confiscated by various governments. Does this mean that only those that can trace their roots back to Hudson Bay employment are Metis?
The Jesuits used more than just Metis as guides. They used who they could get, whether that be Metis, Indian or Voyageurs.
