The St. Caillins club represents a small parish, Fenagh, and part of the parish of Gorvagh, which are nestled in the center of south Leitrim.

The club is steeped with history having been one of the first clubs to be set up in Leitrim in 1888. The club has won 5 Leitrim Senior Championship titles, although the most recent was back in 1932.

The Fenagh Perpetual Cup was presented by Dick Ellis, Fenagh to Leitrim County Board and is awarded to the County Senior Football Champions each year.
