I., which was granted to John Allee, at the Reformation. It contains 86 houses and a brewery and malting-house, and is a constabulary police station. Fairs are held on July 1st, and Oct. 17th. It is a chapelry, in the diocese of Kildare, annexed to the benefice of Geashill, and has a large ancient chapel. In the R.
