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 Eryrys was formed by an Order in Council on 11 October 1861, from parts of the townships of Eryrys, Cyfnant, and Gwaunyffynnon, which had until then been in the parish of Llanarmon yn Iâl.
