No, Mary, unfortunately I don't. But...my best guess is they are from Acadian descent, and is most likely the same Hébert lines as mine. From the little I do know, a lot of Acadians went to Louisiana, New Orleans, and most probably South Carolina during the expulsion in the 1700's??. A good site to look for information (if you haven't already found this...is
www.acadian-home.org). You will need to find your grandparents marriage (or death/baptismal) information first...before you can speculate her lineage, however, as it deals with historical information. Once you find her parents, it will be easier going for you to continue upwards with her line! Good Luck to you!!!!
P.S.: I descend from both Hébert lines (Louis Hébert and Marie Rollet), and the Acadian Hébert line.
Take care,
Denise
