Denis O'Conor held a property including a mill, valued at £10, at Kilcorkey, barony of Castlereagh, at the time of Griffith's Valuation. In 1749 the Census of Elphin recorded Richard Rutledge, gentleman, as the holder of a property in Kilcorkey. A house and extensive outbuildings still exist at the site but both have been modernised. The outbuildings have been coverted to living accommodation. An impressive standing stone is visible in the field close to the rear of the house.
