The surname Lacasse comes from the region of Gascogne in southwest France. It was a name for someone who lived in Gascoigne.

John de Caleto or Caux (d. 1263), Treasurer of England, was "probably a native of the Pays de Caux. By Matthew Paris he is called John of Caen (Johannes de Cadamo), and other writers give his cognomen in the various forms De Calceto, De Cauz, De Cauaz, De Caus, and De Chauce. The Peterborough chronicler, Walter of Whittlesea, who wrote in the fourteenth century, states that he was born in Normandy, of a noble family, being related to Eleanor of Provence, the queen of Henry III, and entered the monastic life when a child seven years of age. Coming over to England at an early age, he became a monk of the monastery of St. Swithhun, Winchester, of which he was chosen prior in 1247." 1

In the 1700s, land incentives were finally given out by France to 2,000 migrants. 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, Acadia 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.
