I think that we can be sure that our common ancestor, Pierre Couturier, was born in the Poitou-Charentes region of France. I've been unable to find the little village. Perhaps, it no longer exists. I would assume that Couturier was with this detached Swiss regiment in Louisiana because he was an army surgeon, not that he was Swiss. Since the Baudiers were also French army surgeons, I am very interested in this line of research. I now have a very good contact in SE France. He is researching about the nature of army surgeons during that time period for me. Rochefort is just east Lyon and just north of Grenoble. I guess because of the whole SE border issue mentioned in the article, this whole area was military industrial complex during this time period. I have another contact in Lyon who helps with that research. Because we know Couturier was from the Bishopric of Poitou, documents about that branch of our family in France are probably available. ~Bonnie
