The cemetery for Notre-Dame-du Mont-Carmel (Concession) Parish is located on the Second Division Road, approximately half a mile from Notre-Dame-du Mont-Carmel church.
This cemetery has also been indexed by another researcher, providing valuable additional information.
Many thanks to Jason N. Gaudet who has granted me permission to post the link to his cemetery gravemarker indices. This link takes you to a page which functions as a portal to various gravemarker sites, hosted on a Charlotte County website.
