The glebe-house was erected by aid of a loan of £350 and a gift of £450 from the late Board of First Fruits, in 1816; the glebe of the union comprises 18a. 2r. 16p. The church was rebuilt by aid of a grant from the same Board, about 1835. There are two private schools, in which about 80 children are educated. There are some remains of a castle that formerly belonged to the Fitzgeralds; and of Mount Rice, a large mansion erected by the Rice family.
