At the time of Griffith's Valuation, Leslie O'Callaghan was leasing this property from Eustace estate when it had a valuation of £8. In 1942 the Irish Tourist Association survey noted that the ruins of what had been a Nagle property were still visible to the rear of Rockvale. The Survey also recorded that Leslie O'Callaghan, who "had lived there about 100 years ago" had been killed in Cork and that the property had come into the ownership of the Annesley estate. It was later sold to the Patterson family and the house is still extant.
