The surname Onstansoux was first found in Languedoc, where the earliest known bearers of this name are thought to have originated. However, the Onstansoux name was found in several regions from quite early times, with several different, perhaps even unrelated families taking on the surname. There was a noble family of feudal lords bearing the name in Poitou in the thirteenth century, and later, in the fifteenth century, there was another prominent family of that name among the nobility who held large fiefs in Brittany.

Walter Coutances (de Constantiis), (d. 1207), was "Bishop of Lincoln and Archbishop of Rouen, and is said to have been of English birth, the son of Rainfred and Gonilla; John de Schalby, in his compilation from the Lincoln records, states that he was a native of Cornwall. He may have been called of Coutances as he was sprung from the house of Corineus, the fabulous Trojan immigrant into Cornwall. He was clerk to Henry II and his eldest son, and is styled chaplain of Blythe. " 1

French settlers came early to North American, following in the wake of the explorers, and creating New France. Quebec City, founded in 1608 by Samuel de Champlain is said to have been the first American site founded as a permanent settlement, rather than as just a commercial outpost. But emigration was slow, in 1643, 109 years after the first landings by Cartier, there were only about 300 French people in Quebec, and by 1663, when the region was officially made The Royal Colony of New France, by Louis XIV, there still only around 500 settlers. Over 2,000 would arrive during the next decade. Early marriage was desperately encouraged amongst the immigrants. Youths of 18 took fourteen-year-old girls for their wives. The fur trade was developed and attracted immigrants, both noble and commoner from France. By 1675, there were around 7000 French in the colony, and by that 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. Despite the loss of the Colony to England, the French people flourished in Lower Canada.
