Duguay-Trouin (French privateer)
During the late 18th and early 19th centuries, many French privateers and letters of marque bore the name Duguay-Trouin, named for René Duguay-Trouin: René Trouin, Sieur du Gué (10 June 1673 – 1736), French privateer, admiral and Commander in the Order of Saint Louis. Between  1760 and 1810, warships of the Royal Navy captured seven different French privateers all with the name Duguay-Trouin.
