Joseph-Claude Boucher de Niverville

Joseph Boucher de Niverville (September 22, 1715 – August 30, 1804) was an army and militia officer in New France (under the rule of the Kingdom of France) and the Province of Quebec (under the rule of Great Britain) of present-day Canada. He was made a Chevalier of the Order of Saint Louis and his military career was "one of the longest of any Canadian officer in the 18th century."

In 1751 Niverville was ordered to establish a new trading post west of Fort Paskoya (Le Pas) to serve as a base for an expedition west towards the Rockies. He dispatched two canoes with ten men from Fort Paskoya but he himself became ill and could join them as he had intended. His men built Fort La Jonquière (probably in the vicinity of Nipawin, SK) and possibly even went far enough west to sight the Rockies. In December of that year Marie was executed by hanging.
