late edit: DISCLAIMER: The pictured map is not actually a representation of the territories before colonisation. It's a hypothetical map of what countries there might have been had the continent not been colonised, thus all the names and borders are fictional and have never existed.
For good actual maps, check out native-land.ca.

People/families like feeling special and unique, a inherited culture is one of the easiest ways to achieve that feeling I guess even if faux.
