In 1868, the parish of Overton contained the following places:
"OVERTON, a parish in the hundred of Maylor, county Flint, 7 miles from Wrexham, its post town, 5 N. W. of Ellesmere, and 5 from the Overton station on the Shrewsbury and Chester section of the Great Western railway. The village which is of small extent, is situated at the bridge over the river Dee. It is mentioned in Domesday Book as Ovreton, and was formerly held by Robert Fitzhugh, Robert de Crevecoeur, the Stranges, and other distinguished families. It is a polling, petty sessions, and decayed market town, and unites with Flint in returning one member to parliament. The parish includes the hamlet of Clog, Knolton, and Maesgwaylod. In the neighbourhood are traces of a castle built by Madoc ab Meredydd, Prince of Powis. The living is a curacy annexed to the rectory* of Bangor-Monachorum, in the diocese of St. Asaph. The church, dedicated to St. Mary, is a cruciform structure. The churchyard contains some yew trees of great antiquity. The parochial charities produce about £34 per annum. There are several residences, including Gwernhaeled, situated in a park, with a camp and barrow, and the residence of Bryn-y-Pys, where the late Duke of Wellington passed his childhood. Annual fairs are held on the Monday prior to Holy Thursday, 11th June, 9th August, and 8th October."
