1973 Report on the Pembina Band defines Metis
"Metis (French for "half") does not merely mean "half blood" or "half breed", but has a much broader connotation, referring to a large cultural and sociological element formed during the buffalo hide trading era in the northern Plains. The Metis have French and other European ancestry, and Plains Chippewa, Plains Cree and other Indian ancestry. By the early part of the last century the Metis had developed a distinct culture, marginal to that of the tribal peoples and the anglicized societies of both the United States and Canada. They were also linguistically distinct, having developed the "Metis jargon" which is sometimes called "Cree" but is predominantly French with many Chippewa and Cree elements."
