In 1786 Wilson mentions Oranmore as the seat of Denis Blake. In 1814 and again in 1837 Oranmore Castle is recorded as the seat of Walter Blake. At the time of Griffith's Valuation he was leasing a property, valued at £10, in Oranmore townland, to Martin Grady. Pádraig Lane writes that Walter Blake sold Oran Castle to James Dillon Meldon. The castle was refurbished by the King family in the twentieth century.
