"A parish in the Union of Conway, forming a detached portion of the hundred of Creuddyn, county of Carnarvon, and locally within the shire of Denbigh; 4 miles (W) from Abergele, containing 679 inhabitants. This parish, which is extremely mountainous, comprises 1772 acres. ..... A considerable quantity of limestone is quarried from the rocks here, and shipped at Llandulas Bay for Liverpool. The village consists of five houses only."
[ A Topographical Dictionary of Wales, 1833 & 1849, Samuel Lewis]
The ancient parish comprised the townships of Isallt, Isyffordd, Pant ( or Tre'r Pant), Penmaen and Rhwngyddwyffordd.
Historically, until 1 April 1923, it was a completely detached portion of the commote of Creuddyn (Caernarfonshire).
In 1872, part of the parish was lost to Colwyn; but, at the same time, it gained part of the township of Twynnan, from the parish of Llanelian yn Rhos.
