Hugues McRoonan (1739-1804) was an Irish-French soldier who served in the French Royal Army's Irish Brigade during the Seven Years' War and the American Revolutionary War. Born in France, the son of Francois McRoonan, he joined his father's regiment during the Seven Years' War and fought in Picardy in 1760. He later accompanied his regiment to the Caribbean during the American Revolutionary War, and he was wounded at the Siege of Savannah and left in the care of his American allies after his regiment was withdrawn. McRoonan, who was taught English by his family, became a drill instructor for the Continental Army, sharing his European training with American Patriots. McRoonan fought at the Siege of Yorktown, during which he served as a translator for the French and American armies, and he ultimately chose to stay in the United States after being offered a major's rank in the Georgia militia. McRoonan settled in Savannah, where he fathered three children, including Rochambeau McRoonan. He became a Federalist due to his monarchist and conservative tendencies, and he died in 1804.
