Family[edit]
Medieval Welsh tradition held that he was related to Hywel, a legendary Brythonic king of Brittany. He is said to be one of Hywel's sons in a late version of the genealogical tract Bonedd y Saint. Welsh tradition also makes him a brother of Sts. Tudwal and Arthfael (also reputed sons of Hywel), and a cousin to Saint Cadfan.
In fiction[edit]
A fictionalized Derfel Cadarn is the main character in Bernard Cornwell's historical fiction/historical fantasy novel trilogy The Warlord Chronicles, retelling the story of King Arthur in Dark Age Britain.
