I've been reading your past emails. I'm probably a distant cousin. I'm the daughter of Ovila,son of Leon, son of Venance. My father passed away this year. We found an old picture of all of Venance's sons and daughters and their spouses. My Dad's sister, Adeline identified all the couples. If you would like me to email the picture, just ask. My search for my ancesters ended the same place as you with Jacques Nouvion dit SansCartier 1763.
Hope to hear from you
