Métis
The Métis ( ; ] ) are a multiancestral indigenous group whose homeland is in Canada and parts of the United States between the Great Lakes region and the Rocky Mountains. The Métis trace their descent to both Indigenous North Americans and European settlers. Not all people of mixed Indigenous and Settler descent are Métis, as the Métis is a distinct group of people with a distinct culture and language. Since the late 20th century, the Métis in Canada have been recognized as a distinct Indigenous peoples under the Constitution Act of 1982 and have a population of 587,545 as of 2016. Smaller communities self-identifying as Métis exist in the United States, such as the Little Shell Tribe of Montana. The Métis ethnogenesis began in the fur trade and they have been an important group in the history of Canada, as well as the foundation of the province of Manitoba. The Métis have homelands and communities in the U.S., as well as in Canada, that have been separated by the drawing of the U.S.-Canada border at the 49th parallel North. Alberta is the only province in Canada with a recognized Métis land base, the eight Metis Settlements, with a population of approximately 5,000 people on 1.25 million acres.
Constantine Scollen
Father Con Scollen OMI. (4 April 1841 – 8 November 1902) was an Irish Catholic, Missionary priest who lived among and evangelized the Blackfoot, Cree and Métis peoples on the Canadian Prairies and in northern Montana in the United States. He also ministered to the Kootenay peoples on their annual visits to Fort Macleod, from British Columbia. Later he worked among the indigenous peoples in modern-day North Dakota and Wyoming, then Nebraska, Kansas, Illinois and Ohio.
Constantine Scollen
He is particularly remembered for having the first building erected (by Alexis Cardinal, a Cree speaking Metis) in what is now, Calgary, Alberta, in 1872. In 1876 he was an unofficial interpreter for some of the Plains Cree Chiefs (Peter Erasmus Jnr., a half Danish Metis, Methodist minister, was interpreter for the other chiefs and Governor Morris) and witness to Treaty 6 between the Cree and the Canadian government. (The Woods Cree and Swampy Cree made a separate treaty with the Canadian government) He was an unpaid consultant to the Canadian government prior to the signing of Treaty 7 with the Blackfoot Confederacy, in 1877 and was again an unofficial interpreter and witness. Jean L'heureux became official interpreter because of the shortcomings of Jerry Potts. Scollen took great care to avoid politics but following the failure of the Dominion government to fulfill its treaty obligations, he became very outspoken, on behalf of the native peoples and remained so for the rest of his life. In 1870, he had spent the winter at Rocky Mountain House, co-writing a Cree language grammar and dictionary with his mentor, fellow Oblate and friend, Father Albert Lacombe. His considerable contribution was not acknowledged on publication. (""Dictionnaire de la langue du Cris.1874", "Grammaire de la Langue Cris.1874", "Instructions en Langue Crise sur toute la Doctrine Catholic.1875" and "Petite Manuel pour appredre a lire Langue Crise 1886"") There was a further, much later publication entitled "Prieres Cantiques, Catechisme en Langue Crise 1980" which was derived from the original work but accredited to Lacombe only. Scollen also wrote a book of 75 sermons in Cree, for Oblate, Father Joseph Dupin.
