Delachaux History, Family Crest & Coats of Arms
The surname Delachaux 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."

Migration of the Delachaux family
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. Among settlers to North America of the Delachaux surname were W. Casse, who arrived in Bermuda in 1635 at the age of 19; Antoine Lacasse-Casse, who settled in Quebec in 1665; Valentin Casser, who settled in Philadelphia in 1748.
