What do you mean exactly by relatives? Descendents or ancestors or both? I know that Alexis was born Abt. 1788 son of Pierre L'Esperance and Marguerite Aucoin. He came to Red River in 1816 from Sorel, Quebec. His daughter Adelaide had atleast three children with Michel Dumas, Michel b. 1 Dec 1948, Julie b. 6 Jan 1851 and Pierre born 6 Oct 1855. I believe Michel was the son of Michel Dumas and Marguerite Sanson?.
