Daniel-Marie Chabert de Joncaire de Clausonne

Daniel-Marie Chabert de Joncaire de Clausonne[a] (c. 1714 – 1771) was a French army officer and interpreter in New France who established Fort du Portage near Niagara Falls and fought in the French and Indian War.

[2] He also lived with the Ottawa, Ojibwa, and Shawnee and later married the Seneca Marguerite-Élisabeth-Ursule Rocbert de La Morandière in Montreal.

[2] Upon his return, Joncaire was implicated in the Canada Affair during the Seven Years' War and consequently imprisoned in the Bastille.

[2] During his trial, his defence was based on records which were destroyed when he burned down Fort du Portage; the court found him guilty of carelessness in his inventories of provisions in 1763 but effectively acquitted him with a warning against future recurrences.

[2] In 1764, Joncaire went to London and unsuccessfully asked King George III for the land of the former Fort du Portage.
