First found in Brittany, where they are recorded as an ancient family with lands, manors and estates.

By 1643 there were only about 300 people in Quebec. Since immigration was slow, early marriage was desperately encouraged amongst the immigrants. The fur trade attracted migrants, both noble and commoner. 15,000 explorers left Montreal in the late 17th and 18th centuries. By 1675, there were 7000 French in Quebec. By the same year the Acadian presence in Nova Scotia, New Brunswick and Prince Edward Island had reached 500. In 1755, 10,000 French Acadians refused to take an oath of allegiance to England and were deported to Louisiana. The French founded Lower Canada, thus becoming one of the two great founding nations of Canada. The distinguished family name Cadeaux has made significant contributions to the culture, arts, sciences and religion of France and New France.
