The parish of Drumreilly derives its name from Druim Airbhealaigh "the ridge of the eastern pass". The parish is centered on the medieval island church in Lough Garadice, whose ruins are extant today. All churches of the parish, and one townland, inherited the parish name. The parish of Oughteragh contained a church located on a high hill one kilometre north of present-day
Ballinamore. The church, and nearby holy well, were dedicated to Saint Brigid. There was a hospital dedicated to Saint John the Baptist, located at the (Ballinamore) ford over the Yellow River. Both parishes were joined together to form the "Rectory of Cinél Luacháin". This is confirmed by the Annates for 1423 (p. 230) which state "rectoria parrochialium ecclesirum de Drumreilly et Oughteragh alias de Kenel Luchan vulgariter nuncupata". The rectory corresponded with the territory of the Conmaicne of Luachain. ==See also==
