Early Origins of the Ladue family

The surname Ladue was first found in Brittany where they held a family seat in the honor of the seigneurie of Blardais, Busnelaye, and Rouvray.

By the 13th century they also branched to St. Sulspice in Normandy. Members of the Norman branch became seigneurs, and in this region they held a family seat at Duquerie. The family gradually, over the next three or four centuries, moved eastward to île-de-France, to Hainaut and finally to Flanders (Belgium).

In the latter region they held a family seat at Masnuy-St.Pierre, and members of this branch became knights in 1735. In Flanders they were Barons in 1787, just before the revolution, and intermarried with the distinguished family of Miche. In île-de-France they held a family seat at Fontaine. They also acquired estates in Perche, Champagne, Marche, and Gascogne.

Jean Leduc, born in 1624, travelled from Ingre, France to Canada in 1652. After arriving in Quebec he worked as a sawyer and he married Marie Soulinie, born in 1631, on 11th November 1652. The Lords of the Isle of Montreal gave Jean an acre of land on 20th August 1655 and this is where he settled with Marie. Jean and Marie had six children together, all boys, that all have many ancestors with the name Leduc in Canada. [1]

Migration of the Ladue 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 Ladue surname were Jean Leduc who arrived in Saint Omer, Quebec, from Perche on the southern border of Normandy in 1652; Antoine-Pierre Leduc arrived in Quebec from Normandy in 1681.
