I checked all my resources and may have found your Joseph.
I believe your Joseph A. may be Joseph Anthony Pourciau because I have a Joseph Anthony that married an E. Lemoine in my records but no dates. Can you tell me their children? Or anything more. What about her family? While Lemoine wasnt nearly as common in PC as Pourciau back then, it was pretty common and this may not be your family.
Pourciau, Gremillion, Jarreau, David, Delage, Saizan, Bergeron, Patin of PC.
