Jean-Baptiste Louis Frédéric de La Rochefoucauld de Roye, Duke of Anville (17 August 1707 – 16 September 1746), Marquis of Roucy, who was made the Duke of Anville by King Louis XV of France and pursued a military career in the French galley corps.

The expedition was composed 20 warships, 21 frigates, and 32 transport ships, containing 800 cannons, 3,000 soldiers, and 10,000 marines.

The French fleet was dispersed by a storm between Sable Island off Nova Scotia to as far away as the Caribbean.

[3] The corpse of the Duke was transported to Louisbourg, Île Royale (Cape Breton Island) in 1748, and finally to France.

As his father-in-law had no surviving sons, he was granted permission by the Pope and by letters patent of the French King to transmit the ducal title to the male issue through the female line on the condition that his daughter marry a member of the La Rochefoucauld family.
