Etymology of Lacasonne

What does the name Lacasonne mean?

The surname Lacasonne 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

Migration of the Lacasonne family

France was active as a cultural leader in the early 16th century. One particular area in which they lead was the exploration of the New World. The explorers, like Jacques Cartier in 1534, led the way to North America. Champlain, in 1608, made the first of twenty voyages to France to attract settlers and brought the first migrant in 1617. By 1675, there were 7000 French in Quebec, and the French Acadian presence in the Maritimes had reached 500. The French founded Lower Canada, thus becoming one of the two great founding nations of Canada.
