From A Topographical Dictionary of Ireland, 1837
KILLEENEY, a parish, partly in the barony of DUNKELLIN, but chiefly in that of KILTARTAN, county of GALWAY, and province of CONNAUGHT, 4 ½ miles (N. W.) from Gort, near the road from that place to Kinvarra; containing 820 inhabitants, and 5931 statute acres, as applotted under the tithe act. The land is very coarse and rocky, and the only seat is Normangrove, the residence of John Burke, Esq. It is a vicarage, in the diocese of Kilmacduagh, forming part of the union of Kilcolgan; the rectory is appropriate to the see, the deanery, and the vicarage of Ardrahan.
The tithes amount to £98. 0. 6., of which £21 is payable to the Ecclesiastical Commissioners, £7. 7. to the dean, £42 to the incumbent of Ardrahan, and £27. 13. 6. to the vicar. There are some remains of the old church, with a small burial-ground attached. About a mile from Kinvarra is a hole in the rock, called the Pigeon Hole, which leads to a natural cavern, three or four hundred feet in extent. Here are the remains of the castle of Cahir Irlane, which is said to have belonged to the Killikellys.
