Bonjour,
I remember that in the past time I've had in my hands this booklets :
http://www.patrimoines.lorraine.eu/index.php?id=61&tx_sr... and
https://books.google.fr/books?id=YJLykWEN5XMC&pg=PA107&a...They are in French but the Lorraine immigration seems to start around 1720 and finished about 1770/75.
If you have the info on your first ancestors I will try to search about them.
Here is the mail adress of "Cercle généalogique de la Moselle"
http://www.moselle-genealogie.net/quickcart/?p=p_1&sName.... NOT for FREE but try to ask.
Break a leg ?????
