I am also a descendant of Etienne Penisson.My grandmother was Thelisia Marie Penisson (7th child of Etienne Ulysse Penisson)and my grandfather was Alcee Henry Rentrop, III (son of Alcee Henry Rentrop, II and Marie Roselie Penisson)
I have a 1988 copy of a book "The Penisson Family - France to Louisiana".Is there an updated version of this book?The copy that I have is about 103 pages long.
The book was compiled by Nora Della Penisson Rock and published by St. Mary Genealogical Society, PO Box 662, Morgan City, LA 70381.
I have been unable to find out anything on the St. Mary Society as whether there are still around or what.
Penelope, If you send me your full birth name, I will try to see what is listed in the book and let you know. I looked up Bauer, but did not see anything listed in the index.This book only goes as far as the middle 1980's, so you may have to send my your parents names.
