The Drumlish Heritage & History Society is a community-led organization dedicated to researching, preserving, and promoting the local history and heritage of Drumlish and Ballinamuck. Established in 2012, the society works to redress the historical absence of visible heritage reminders in the area. Their impact includes the publication of local history books, the creation of the Drumlish Heritage Trail, the installation of commemorative panels and sculptures, and the ongoing maintenance of local historical sites like Kilmahon Graveyard.
