Guy, I do not have any data on Onesime and Marie. Also, all of my family spells their last name ending in "t", not "d". If we both actually are descendants of Pierre Daspit de St. Amant I do not have any record of that connection. My great-great-grandfather was Major Alexis Alexandre St. Amant born 1760 and married Anne Zeringue, my great-grandfather was Venance St. Amant born 1800 in New Orleans, married Amalin Asselin, and my grandfather was Francois Alfred St. Amant born 1846 in St. John Parish and married Sarah Lucy Haile. Does this make any connection to your ancestors?
