The third in the series of Fur Trade Families of Quebec is ancestor Martin Prevost or Provost. He arrived in Quebec before 1639. He was settler and farmed near Beauport, Quebec. He married on 3 November 1644 at Quebec. Marie-Olivier, the daughter of Roch Manithabewich, a Huron (or maybe an Algonquin) Indian, and adopted daughter of Olivier Letardif. Together they had eight children whose descendants continue to the 21st century. Martin Prevost remained in Quebec. His wife Marie-Olivier died on 10 September 1665 when her youngest child was only 3 months old. He married Marie d’Abancourt two months later. They had no known children. Marie d’Abancourt was the widow of Jean Jolliet and widow of Godfroy Guillot dit Lavallee. She died between 1678 and 1681. Martin remained unmarried until his death in 1691 at Beauport (Quebec). His surviving children and grandchildren were all living near Beauport. They were farmers, laborers and merchants and appear to have assimilated into the non-Indian culture. In the seventh generation the Prevost descendants are living in the Oregon Territory, Alberta, and Manitoba and have once again married mixed blood wives. Notable descendants of Roch Manitouabeouich, father-in-law of Martin Prevost are Jean Baptiste Lepine, Stephen Liberty, Louis Provo, Joseph Salois, and Joseph St.Germain dit Brissard.
