Hi Barb I would like to help but I am a bit confused with your info. I have Charles Richer Lafleche married to Marie Josphe Hamelin in Grondines 2 January 1755 but I have no son Louis born to them on May 4 1767 According to the PRDH U of Montreal their son Louis was born 23 August 1772 and married Marie Anne Renaud Sanschagrin. He could have remarried but his Mother Marie Josephe Hamelin could not possibly have been born 20 August 1760 as she would have been age 5 when she married and 7 when Louis was born. Marie Josephe Hamelin who married Charles Richer Lafleche was born 30 March 1732 Grondines. Her parents Joseph Marie Hamelin and Marie Genevieve Dechavigny. Marie Josephe died 18 May 1789.
