MORTLESTOWN, a parish, in the barony of IFFA and OFFA, county of TIPPERARY, and province of MUNSTER, 1? mile (N. by E.) from Cahir, on the road from Clonmel to Cashel ; containing 574 inhabitants, and comprising 1835 statute acres, as applotted under the tithe act. It is a rectory, in the diocese of Lismore, forming part of the union of Outragh ; the tithes amount to #150. An improper presentation to this benefice was one of the charges brought against the Earl of Strafford, when impeached by the English parliament. Here are the ruins of a castle, which appears to have been formerly of considerable extent.
