Found a Jean Baptiste Lecompte who married a 'Saucier' in Cahokia in 1809. Does anyone know his parents?
Also there was a Marie Marguerite Lecompte who married Pierre D'Amour De La Louvier in May of 1791. Her parents were Aime LeCompte and Catherine Allard, probably from Quebec. I have a Jacques Lecompte married to a Therese Loiselle, living in Illinois Territory, but exact date, but born about or shortly after 1730.
I wonder who the original Lecompte was who settled Illinois territory?
