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 Rossett was formed by an Order in Council on 30 June 1840, from the townships of Allington (Trefalyn), Burton, and Marford & Hoseley, which until then had been in the parish of Gresford. In November 1851, part of the township of Gwersyllt was transferred from Rossett to the new parish of Gwersyllt [Information taken from http://www.genuki.org.uk/big/wal/DEN/Rossett/index.html (last accessed July 2015)]
