are these 2 names inter-changeable? I am looking into Louis Sansfacon (consigny) and Madeleine thibodeau. I am wondering if there are 2 couples with the same names. I a have found 2 different  sets of parents. date that are way off. the couple I am tracing are from St-Basile, Madawaska, New Brunswick, yet I find a marriage for a couple in St-Louis, Kamouraska. in 1764, yet Louis is said to have been born abt 1757. 2 kids born 1764 & 1765 in Kamouraska. the others abt 1783-84 in Madawaska. and marrying there. Any help greatfully accepted. To make matters worse Louis is sometimes a Consigny and other times a Sansfacon Selma
