DERRYHEEN, a district (ecclesiastical), in the barony of UPPER-LOUGHTEE, county of CAVAN, and province of ULSTER, 3 miles (N. W.) from Cavan, on the road to Enniskillen; containing 1771 inhabitants. This place was erected into an ecclesiastical district in 1834, by disuniting nine townlands from the parish of Urney, three from that of Kilmore, three from Castleterra, and a portion of the parish of Drumlane. It is situated on the river Derryheen, and contains some good arable and pasture land in a state of improved cultivation, though partially subject to occasional inundation from the surrounding lakes, and a moderate portion of valuable bog. The living is a perpetual curacy, in the diocese of Kilmore, and in the patronage of the incumbents of the parishes out of which it was formed: the income of the curate arises from a money payment contributed by each of the patrons. There is neither glebe-house nor glebe. The church is a neat and wellbuilt edifice. A school at Dedris is supported by Lord Farnham, and there is one at Inishmore, together affording instruction to about 100 boys and 60 girls. Here are the ruins of some ancient buildings, called Church Urney, supposed to have been monastic: they form apicturesque object, with a burial-ground attached, used by the R. C. inhabitants.
