On October 31, 1767, Barry married Mary Cleary, who died in 1774. On July 7, 1777, he married Sarah Austin, daughter of Samuel Austin and Sarah Keen of New Jersey. Barry had no children, but he helped raise Patrick and Michael Hayes, children of his sister, Eleanor, and her husband, Thomas Hayes, who both died in the 1780s. Barry died at Strawberry Hill, in present-day Philadelphia on September 13, 1803, and was buried in the graveyard of Old St. Mary’s Roman Catholic Church in Center City, Philadelphia. He commanded Lexington, Raleigh, and Alliance. He and his crew of the Alliance fought and won the final naval battle of the American Revolution off the coast of Cape Canaveral on March 10, 1783. He was seriously wounded on May 29, 1781, while in command of Alliance during her capture of HMS Atalanta and Trepassey. Barry was successful in suppressing three mutinies during his career as an officer in the Continental Navy. He was still in command of the Alliance when it participated in the last battle of the Revolutionary War.Appointed senior captain upon the establishment of the U.S. Navy, he commanded the frigate United States in the Quasi-War with France.
