Hi Nick: You ask about the women married to Rossignols. Taking a chance, I looked up the Bois ,Ouellet, Caron and Michaud lines for you. The Ouellet line was defective. The parents' names weren't on the marriage record, and census records came up inconclusive. I did get the Bois, Caron and Michaud lines done though. I also did the Durepos and St-Amand lines even though you didn't ask for them. Good thing I did too! Guess what? I found you nobility and royalty!
If you're interested, I'll send you these lineages.
