The champagnes that you are looking for are the descendants of Pierre Champagne and Antoinetee Thibaut. The son Jean Baptiste Champagne came to this counrty as a French marine approx. 1714. He was living in the Bishophric of Rheams when he left France as a marine. I have been doing research for over 15 years and have found transcripts of the Louisiana Superior Council, Baptism, marriage and death records, along with marriage contracts and property purchases. I have a translation of Jean Baptiste, I inventory of his estate. I would be happy to answer any questions that you might have-I have a huge amount of detailed info of the Champagnes and their wives family.
