In 1868, the parish of Dysert contained the following places:
"DYSERT, (or Dysert O'dea), a parish in the barony of Inchiquin, in the county of Clare, province of Munster, Ireland, 3 miles S.E. of Corrofin, its post town. It is situated on the river Fergus. The surface is broken and mountainous, and subject to the overflowings of several minor streams and loughs. The living is a vicarage in the dioc, of Killaloe, value with Kilnaboy, £432, in the patronage of the bishop. There are a Roman Catholic chapel and three day schools. There are two police stations, and a manor court is occasionally held. This parish formerly belonged to the sept Dysert O'Dea, and was divided into Inach and Ruan. There are ruins of churches said to have been built during the time of Turlough O'Connor; that of Dysert has a remarkably fine doorway; near it are the remains of a round tower, with traces of windows and doors. A stone cross, bearing a supposed effigy of St. Monalagh, may also be seen. The ruins of Dysert Castle, the ancient seat of the O'Deas, are particularly interesting.
