In 1749 Richard Kirwan was living at Coristoonamore. This house appears to have been the residence of K. Lyster [Kirwan Lyster?] in 1814 and of F.T. Byrne in 1837. Occupied by Patrick O'Connor in the mid 1850s, who held the house from Christopher Hamilton. Valued at £2 in 1906 and in the occupation of Sir N. O'Conor. It is no longer extant.
