This parish, which derives its name from the dedication of its church to St. Baglan, is situated on the Menai strait, near its southern extremity, and comprises only a few farms and widely scattered dwellings. The living is a perpetual curacy, annexed to the vicarage of Llanwnda, in the archdeaconry and diocese of Bangor : the great tithes are appropriated to the Principal and Fellows of Jesus' College, Oxford. The church, situated in the centre of a large field, to which there is no public road, is an ancient edifice, consisting of a nave and chancel, with a spacious chapel on the north side : the eastern gable is ornamented with the remains of an ancient cross, curiously sculptured. The average annual expenditure for the support of the poor is £ 68. 13. ( A Topographical Dictionary of Wales by Samuel Lewis, 1833)
