Thomas Frewen was leasing this property to James Corker at the time of Griffith's Valuation, when it was valued at £16 10s. In 1837 it was the seat of Chambre Corker. Cor Castle was in ruins for many years following its burning in June 1921 during the War of Independence. At the time it was the residence of Mrs. Carolne Stephenson, who, Donnelly indicates, had inherited it from her mother, Sophia Corker. It has recently been restored.
