Hi JoAnne, Much more Duguay than Loisel are in my lines. Loisel is in my collateral lines. Romain Duguay,son of Pierre and Marthe Roussy) married Sophie Loisel. Sophie dau. of Jean and Rose Duguay. Who did your Francois-Xavier marry? I presume he was son of Sophie and Romain. Who do you have for the parents of Pierre married to Marthe Roussy? Send me your line and I will see where we connect. I will share any info. you need. Have a nice day! Rose Ashland,MA
