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. Following a decision by the Church in Wales to group parish collections by deanery, the records of Rhuddlan were transferred from Flintshire Record Office to Denbighshire Record Office in June 2009.
Rhuddlan is one of the ancient parishes of Flintshire, featuring prominently in the Domesday book; at which time it was a stronghold of Robert, the nephew of Hugh Lupus, Earl of Chester. On the 23rd May 1844, the townships of Rhyl and Brynhedydd were lost to the new parish of Rhyl; and more land was transferred from the parish of Rhuddlan to Rhyl shortly after the opening of the district church of St. Ann in 1896.
