The U.S. ship SYLVIE [occasionally: SILVIE] DE GRASSE, was built at Hartford, Connecticut, by D. & H. Burgess in 1833, for the Old Line (later called the Union Line) of sailing packets between New York and Le Havre. 641 tons; 140 ft 6 in x 31 ft 8 in x 15 ft 10 in (length x beam x depth of hold). She was named after Sylvie de Grasse, daughter of the French admiral who had made possible the American victory at Yorktown, and wife of Francis Depau, a native of Bayonne, France, who had emigrated to the United States by way of Haiti, and was the co-founder and principal owner of the Old Line. The vessel was sold for California in 1848, and in September 1849 struck and sank at the mouth of the Columbia River with nearly a half million feet of lumber aboard.
