Thanks so much for your response. I eventually found quite a lot on the D'Arensbourg/Vial lines published in Les Voyageur by Wayne Vial. Although not directly a part of my lines, I do have a connection to a grandson of Emile and Marie Aurelie Chabeau. He is an elderly gentlemen, and was quite astounded with what I was able to find had been written about his maternal ancestors. As he had provided information to help me find my Lost ggrandfather, I was glad to be able to give him something in return.
