France finally gave land incentives for 2,000 migrants during the 1700s. Early marriage was encouraged in New France, and youths of 18 took fourteen-year-old girls for their wives. The fur trade was developed and attracted migrants, both noble and commoner from France. 15,000 explorers left Montreal in the late 17th and 18th centuries, leaving French names scattered across the continent. The search for the Northwest passage continued. Migration from France to New France or Quebec, as it was now more popularly called, continued until 1759. 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 the treaty of Utrecht, the Acadians were ceded by France to Britain in 1713. In 1755, 10,000 French Acadians refused to take an oath of allegiance to England and were deported. They found refuge in Louisiana. Meanwhile, in Quebec, the French race flourished, founding in Lower Canada, one of the two great solitudes which became Canada.

Amongst the settlers in North America with this distinguished name Du Plessier were John Louis Plessis who arrived in Quebec in 1713 from Lorraine.
