From Les Cayes and Fond de Île-à-Vache to Baltimore, Philadelphia and New York City

By 1805, Joséphine Labarrière had evacuated her three children from Les Cayes and Fond de Île-à-Vache (an offshore island of Saint-Domingue), under orders of General Jean-Louis Ferrand (1758-1808), Gouverneur de Saint-Domingue, during the uprisings and revolution. Ferrand remained behind to fight; he eventually committed suicide rather than be captured, though in death he was decapitated and his head placed on a pike. I haven't been able to determine what happened to Paul Valentin Costar, but he seems to have died by 1805, possibly from yellow fever. He was apparently in Philadelphia at the time of the yellow fever epidemic of 1793, which involved a large number of refugees from Saint-Domingue's "troubles." Other members of the Costar family also resided at or near Les Cayes and perhaps elsewhere on Saint-Domingue. Known names include Louis Séverin Costar, a military officer, and Marie Félicité Jeanne Isabelle de Costar. See Généalogie et Histoire de la Caraïbe numéro 141: Octobre 2001, p. 3310. 

As of September 9, 1805, Joséphine Labarrière Costar was living in Baltimore with her children. Presumably she married Jerome De Cressac Villagrand sometime between about 1812 and 1815, by which time they lived in New York City.
