The records of individual ecclesiastical parishes include registers of baptisms, marriages and burials, as well as records of the churchwardens and Parochial Church Councils, parish charities, schools, clubs and societies.
Parish records were deposited at the Clwyd Record Office, following an agreement of 1976 between the Church in Wales and the Welsh County Councils.
The new parish of Pontfadog was formed on 15 April 1848, from the ancient parish of Llangollen. It comprised the whole of Glyn Traean - i.e. the townships of Cilcochwyn, Crogeniddon, Crogenwladus, Erwallo, Hafodgynfor, Nantygwryd, Pennant and Talygarth; and the township of Cysylltau from Llangollen Traean. Cysylltau returned to Llangollen in 1870.
