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.
Although it was a technically a chapelry of the parish of Gresford, in the diocese of St. Asaph, Holt was in the diocese of Chester until 1849, when it was transferred to St. Asaph. It formerly contained the townships of Caca Dutton, Dutton Diffaeth, Dutton y Brain, Hewlington, Holt, Ridley and Sutton; but in 1829, Caca Dutton, Dutton Diffaeth, Dutton y Brain, Ridley and Sutton went to the new parish of Isycoed.
