INISHGEIL, or ENNISGILL, also called INCHAGUILE, an island, in the parish of CONG, barony of Ross, county of GALWAY, and province of CONNAUGHT, 4 miles (S.) from Cong: the population is returned with the parish. It is situated in Lough Corrib, and is about a mile in circumference. Here are the remains of a chapel, dedicated to St. Patrick, and of an ancient religious house, the arches and entrances to both of which are round and the stones carved with human features; and, from being covered with woodbine and ivy, they have a very picturesque appearance. In the churchyard is a tombstone with an inscription, in Irish, to Geill, Ardan, and Sionan, after the first of whom the island, in relation to which many extraordinary traditions exist, is supposed to have been named.
