Tansi;
For generations, Metis people were severely oppressed and extremely poverty stricken, possibly as punishment for having lost a war with Canada, in 1885. Many people began to deny Metis Heritage, as a matter of survival and the ability to "fit in." Often, these people did not inform their children of their Metis Heritage.
There were also many who were Proud of our Heritage, in spite of oppression. Some of these people continued to fight for our Rights and Cultural survival.
In 1982, the Canadian government was forced to acknowledge that the Metis are, and have been, a distinct Culture of Canada's Aboriginal people. This led to the protection of our Rights as Aboriginal people, including language, Spirituality, hunting, gathering and Traditional land use.
This resurgence of Cultural Pride has led to many of the "lost" or "forgotten" people becoming aware of their rightful place with our Metis communities and Culture. Unfortunately, this has also led to many others claiming Metis Heritage, in order to be able to share in our Rights.
I think that the most important issue to consider is in the continuity of Culture. While many Metis people continue to live according to our Culture, some have not had the opportunity and are learning, since rediscovering their Heritage. This has often led to some distortions, especially at the political level, of Metis Culture, but has also brought "home" many people who had been denied their Heritage, through no fault of their own.
Our people come in all colors, often looking Native and often looking non-native. This has always been the case, since we are mixed blooded.
Careful attention is paid to genealogical evidence, showing that there is Metis ancestry, in order to become a member of the Metis Nation. Especially since there was a continuity of Metis Culture, there are still Elders who can remember families and are of great assistance in helping those rediscovering their Heritage in their search.
I do not personally know of the Abenaki situation, so cannot make any suggestions about them.
