A son, Édouard-André Barnard, gained some notability as a militia officer in Lower Canada.
His tenure came to an end on March 27, 1838 when the constitution that ruled the colony was suspended.
He was arrested in November 1838 for his involvement in the Rebellions of 1837 and put in jail in Montreal, but was released in December of the same year.
Barnard eventually made a career as a clerk of court in the Mauricie area and retired in 1878.
