Re: Berteau of Louisiana
It seems we have the same info about Jacques. I do have some info from WorldConnect (which requires a subscription) that he is involved with the family of Pierre Charlet of Mieussy, France. I could find no connection between Jacques and Pierre.
On the Meyer side, my mother's mother's parents were Archibald V. Bertaut and Annie Meyer. Archibald is Jacques' gggggrandson. Any kinship here on either side?
