Daniel-Marie Chabert de Joncaire de Clausonne
French Army officer and interpreter

Daniel-Marie Chabert de Joncaire de Clausonne (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.
Early life
Daniel-Marie Chabert de Joncaire de Clausonne was born to Louis-Thomas Chabert de Joncaire and Marie-Madeleine Le Gay. He was baptized on January 6, 1714 in Repentigny, New France. He was the younger brother of Philippe-Thomas Chabert de Joncaire and was often confused for both his father and brother.
Like his brother, Joncaire was sent to live with the Haudenosaunee at a young age. He also lived with the Odawa, Ojibwe, and Shawnee, and later married the Seneca Marguerite-Élisabeth-Ursule Rocbert de La Morandière in Montreal.
Career
In 1739 and 1740, Joncaire was a cadet, took part of the force sent to assist Jean-Baptiste Le Moyne de Bienville's attack on the Chickasaws in the Chickasaw Campaign of 1739, and then served as the interpreter during the negotiations of the subsequent peace treaty.
In 1748, Joncaire was promoted to ensign. Daniel-Marie replaced his brother Philippe-Thomas as the principal agent for New France among the Haudenosaunee after Philippe-Thomas's resignation. Joncaire commanded the construction of a new fort, called Fort du Portage or Little Niagara Fort, 1.5 miles above Niagara Falls to intercept furs intended for the British at Fort Oswego.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q106311225. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1714, 1771, 1739 and 1740.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources.
