The movement and range of Metis was quite expansive
This is an interesting map showing the breadth and range of Metis movement across their territory. Six (6) ancestors/ancestral families were mapped.
According to results, it appears that the central focus of every single family/person is the Red River settlement area around Winnipeg. Even though hunting areas may have extended as far west as Fort Edmonton, Sweetgrass Settlement in Montana, the Cypress Hills area of Alberta, or as far east as Sault Ste Marie, the focus remains at Red River. These mapped areas would suggest that the idea of a Metis genesis in the Red River region as the central homeland of the Metis Nation is a certainty.
Further, based on data such as this -- that the idea of a Metis "homeland" in the Prairie Provinces (as maintained by the MNC) is a valid position.
Some of the historical communities included in this effort include:
