Duplessie History, Family Crest & Coats of Arms
Normandy is the region of ancient France from which the name Duplessie was derived. It comes from when the family lived in the region of Plessis.
Early Origins of the Duplessie family
The surname Duplessie was first found in Normandy (French: Normandie), the former Duchy of Normandy, where this distinguished family held a family seat at Plessis.
However, we must look to ancient England to find the first record of the family. For is there that we found John de Plessis or Plessetis (died 1263), Earl of Warwick. He was of Norman origin, and was probably a son of the Hugh de Plessis who occurs as one of the royal knights from 1222 to 1227. He was possibly a grandson of the John de Plesseto who witnessed a charter of John in 1204.

Duplessie Spelling Variations
French surnames were subject to numerous alterations in spelling because of the various cultural groups that inhabited specific regions. Eventually, each region possessed its own local dialect of the French language. The early development of the French language, however, was also influenced by other languages. For example, Old French was infused with Germanic words and sounds when barbarian tribes invaded and settled in France after the fall of the Roman Empire. Middle French also borrowed heavily from the Italian language during the Renaissance. As a result of these linguistic and cultural influences, the name Duplessie is distinguished by a number of regional variations. The many spelling variations of the name include Plessis, Plessieies, Plessier, Plessix, Plessy, Plessys, Le Plessis, Le Plessieies, Le Plessier, Le Plessix, Le Plessy, Le Plessys, Du Plessier, Du Plessix, Du Plessy, Du Plessys, Du Plessix, Duplaix, Deplaix and many more.

In 1643, 109 years after the first landings by Cartier, there were only about 300 people in Quebec, in 1663 there were only 500, 2,000 migrants arrived 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 migrants, both noble and commoner from France. 15,000 explorers left Montreal in the late 17th and 18th centuries. Migration from France to New France or Quebec as it was now more popularly called, continued from France until it fell in 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 1755, 10,000 French Acadians refused to take an oath of allegiance to England and were deported to Louisiana. Meanwhile, in Quebec, the French race flourished, founding in Lower Canada, one of the two great solitudes which became Canada.
