KILBEG, or KILMAINHAMBEG, a parish, in the barony of LOWER KELLS, county of MEATH, and province of LEINSTER, 4 miles (N. by E.) from Kells, on the road to Nobber; containing, with the parish of Robertstown, 1478 inhabitants. This parish takes its name from a commandery of Knights of St. John of Jerusalem, founded by Walter de Lacy in the reign of Rich. I., which was a cell to that of Kilmainham, near Dublin, but of which no vestige can be traced. It is a rectory, in the diocese of Meath, and forms part of the union of Newtown: the tithes amount to £180. The glebe-house of the union is in this parish. In the R. C. divisions it forms part of the union or district of Stahalmock; the chapel is in the village of Carlanstown. About 150 children are taught in a school at Carlanstown, which is aided by Sir H. Meredyth, Bart., who also gave a house and an acre of land to the master.
