I have not done extensive research into this line, but it sounds as if you are still into the recent past with your line. Can you get information from other family members?
The further back you go, the more can be found in census lists, other research, etc. The latest census available is that for 1920.
A number of census for St. John the Baptist and St Charles Parishes can be found on line, and much has been written in the German/Acadian Coast Genealogical and Historical Society quarterly, Les Voyageur, on this and other old families of these parishes.
Email me privately, if I can help further.
