According to Scott Ferrel in the genealogy.com forums:
Hi Karen - Just recd your message from Aug. 13 as I normally use a different e-mail address now. I don't believe our LUSSON lines are connected in the US, but Eugene may indeed relate to our family.Here is more on our Lussons:Pierre LUSSON of France m. Jeanne CORMIER.
Their son Jean Louis LUSSON b. Sept. 1754 at Nantes (Loire-Atlantique).Jean Louis LUSSON m. Marie Rosalie MERLIN in Haiti. They fled from Haiti to New Orleans during the Haitian revolution.They had issue:Louis, Marie, Eugenie, Hortense, Eugene (b. New Orleans circa 1806), and Jean Camille Modeste LUSSON (b. New Orleans 1808).The New Orleans port record referring to Eugene in 1823 might relate to this family.
Our line then continues from Jean Camille Modeste LUSSON, who left New Orleans as a young man, emigrating to Cuba where he owned a sugar plantation near Santiago. He married Adele Schweig (or Schueg) in 1833, presumably in Cuba. Adele predeceased Jean Camille, who died in Cuba in 1846, leaving his three children under the care of their maternal grandparents.Of the surviving three children, mentioned elsewhere on this board, the daughter Marie Rosalie (b. 1828) emigrated to France and the two sons (Louis Modeste b.1836 and Pierre Merlin b.1840) emigrated to the United States.
