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.
