Note 16 — II A Selection of George Croghan’s Letters and Journals Relating to Tours into the Western Country—November 16, 1750-November, 1765.

Philippe Thomas Joncaire (John Cœur), Sieur de Chabert, was a French officer resident among the Seneca Indians, to whose tribe his mother was said to belong. Born in 1707, on the death of his father (1740) he succeeded to the latter’s influence and authority among the Iroquois, and made constant efforts to neutralize the influence of Sir William Johnson, the English agent. Joncaire had a trading house at Niagara, and his profits from the portage of goods at that place were great. He accompanied Céloron’s expedition in 1749; and in 1753 met Washington at Venango. It was chiefly due to his influence that the Ohio Indians deserted the English at the outbreak of the French and Indian war. Joncaire led the Iroquois contingent in all the campaigns on the Allegheny and in Western New York; and when Prideaux and Johnson advanced against Niagara, he commanded an outpost at the upper end of the portage. He signed the capitulation of Fort Niagara (1759), but after that nothing further is known of him.—Ed.
