The nearby hamlet of Bryn Saith Marchog (), features in the story of Branwen, daughter of Llyr, part of the Mabinogion, and is so named after Bendigeidfran (Bran the Blessed), who stationed seven princes or knights there (the "Saith Marchog") to watch over his lands while he was away in Ireland. The Lordship of Gwyddelwern was a junior title within the House of Powys Fadog and was recorded in 1400 as being held by Tudur ab Gruffydd Fychan II who was the younger brother of Owain Glyndŵr. Tudur perished in battle during Glyndŵr's war of independence and the title became dormant.
