I have not done much research on it yet, but my great grandmothers name was Selima Mayou. She was married in Coopersville NY (near Altona, NY) to Cyrille Valentin Guerin. I have matched up the real spelling of her last name to Mailloux according to church records. I know that her father was Antoine Mailloux and her mother was Angelique Latouche. She was from a fairly large family. I do have some info on census records from Chazy and Altona listing this family and a couple other Mailloux families in that area around the 1850's thru 1880's.
