The new parish of Rhydymwyn was created by an Order in Council, dated 31 March 1865. It comprised parts of the townships of Gwysaney and Gwernaffield, formerly in the parish of Mold; parts of the townships of Cefn and Glust (or Llysdianhunedd), and the whole of the township of Dolfechlas, formerly in the parish of Cilcain; and part of the township of Caerfallwch, formerly in the parish of Northop. Archdeacon Thomas (1911) states that it also included part of the township of Lygan y Llan, formerly in the parish of Halkyn, but from a study of the township boundaries, that seems to be unlikely.
Ordnance Survey reference SJ 205669.
The foundation stone of the new parish church, dedicated to St. John the Evangelist, was laid on 1 August 1861, and the church was consecrated on 17 September 1864.
The Clwyd FHS website has a photograph of the church.
