Thank you I have many of the older bulletins of L'Heritage, so I will look thru them.
I found a lot of information in Shirley Bourguard's "Early Settlers on the Delta"
many of the families you posted are probably listed there that was baptized in 1852. I believe this book is out of print, but can be found at other libraries in LA and personal collections. Thanks to the many volunteers a lot of the records were transcribed & saved before Katrina hit Louisiana.
Everyone needs to share their genealogy and especially documents that will help others find their family connection.
