Hywel Dda (English: Hywel the Good) or Hywel ap Cadell (c.880 – 950) was a King of Deheubarth who eventually came to rule most of Wales. He became the sole king of Seisyllwg in 920 and shortly thereafter established Deheubarth, and proceeded to gain control over the entire country from Prestatyn to Pembroke. As a descendant of Rhodri Mawr through his father Cadell, Hywel was a member of the Dinefwr branch of the dynasty. He was recorded as King of the Britons in the Annales Cambriae and the Annals of Ulster.[6]


And Howel the Good, son of king Cadell, chief and glory of all the Britons, died. And Cadwgan, son of Owain, was killed by the Saxons. And then the action of Carno took place between the sons of Owain, son of Howel, and the sons of Idwal.[7]

950 - Hywel king of the Britons died.[3]


  1. Darrell Wolcott, The Clan of Tudor Trevor. http://www.ancientwalesstudies.org/id55.html Accessed August 26, 2015. Welsh genealogies are long on pedigrees and short on dates. As a result, the dates sometimes attached to individuals conflict with dates attached to their parents or children. Darrell Wolcott, President, Center for the Study of Ancient Wales, has constructed estimated birth years for those coming before and following Tudor Trevor which seek to resolve the conflicts. Born in Jefferson, Texas in 1935 Darrell Wolcott grew up in Ohio. After a career in banking he took early retirement in 1996, and returning to his place of birth he created and endowed the Center for the Study of Ancient Wales (a non-profit foundation with a library of some 3200 volumes) located in Jefferson, Texas. The foundation has constructed a small castle to house its library and offices and acquired copies of thousands of source and secondary works related to the history of Wales, many of which are otherwise unavailable outside Britain. At present he is its sole researcher.
