Michel-Alain Chartier de Lotbinière, 1st Marquis de Lotbinière (1723–1798), Seigneur of Vaudreuil, Lotbinière and Rigaud, Quebec etc. In 1757, on his advice at the Siege of Fort William Henry, the Marquis de Montcalm successfully attacked Fort William Henry. In 1758, Lotbinière again advised Montcalm to await rather than attack the British Army, at Fort Carillon, the fort that Lotbinière had built, which led to the French victory at the Battle of Carillon. In 1784, Louis XVI of France created Lotbinière a Marquis, the only Canadian by family and birth to have attained that rank, and the last such creation made by Louis XVI. He was the last private owner of Château Vaudreuil in Montreal.
