Born in 1734 in Toulouse, France, where his father was procureur general. He came to Canada, married Jan. 12, 1761, in Montreal, Marie Joseph Larcheveque (first); (second) Louise Auger; (third) Nov. 25, 1776, in Detroit, Theotiste St. Cosme. He came to Detroit about 1768, and soon became a notary and local judge. During Gov. Hamilton's regime, DeJean proved a convenient tool for many arbitrary and tyrannical deeds, one of the most notable being the sentencing of Jean Coutencineau and Ann Wiley to death for robbery in 1776. He, with Hamilton, was captured by Clark in Vincennes in 1779, and sent in irons to Williamsburg, Va. He was paroled, and was active in business in Detroit, Nov., 1781-Jan. 1782. A letter from Normandy in 1786, indicates he had been in France for some time and was proposing to locate in Boston. It is not known when he died. (Blue index cards)
