Bonsoir ou plutôt bonjour Jan, thanks for the quick and very documented response.
At the present time "Etienne" is a widespread surname in France but Etien exists also, particularly in the west part of France as the Charente-Maritime department ( where is located La Rochelle) birthplace of many of exiles. Very few Tienne or Tiene. As for Lavigne it is common enough.
Concerning Pierre Lavigne and Henriette I found informations in the websites http://members.aol.com/_ht_a/MadVintner/myhomepage/RomeWeb/http://members.aol.com/_ht_a/MadVintner/myhomepage/RomeWeb/andhttp://worldconnect.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=madvintner&id=I3542http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=madvintner&id=I3542 Last year I had written to the Webmaster but he had not others informations. Pierre Lavigne was soldier and died in Mobile (burial july 17 1746). He appears in the june 1721 Census, Village of the Apalaches, Mobile. How to obtain a copy of his death record? Are Census results on the Net ? If Pierre was soldier he had probably a "dit" name as you said. It would be perhaps interesting to know the name and origin of his regiment (french or spanish ? ) ?
Thanks to read me and excuse my English, I am French and living in France (you had understood…) Cordialement. Jeanine Thery
