• Notes

  Hywel (pronounced "Howell") Dda ("the Good") was one of the great Welsh princes. He ruled Dyfed, Seisyllwg and Gwynedd and was the founder of the kingdom of Deheubarth. Deheubarth was the most powerful of the kingdoms of south Wales. It was formed in the thenth century by the marriage of Hywel Dda of Seisyllwg to Elen of Dyfed and subsequently extended into Breichinoig. The Welsh 'Brut' called him "the head and glory of all the Britons". He acknowledged the overlordship of Edward the Elder and Athelstan of England and was on close terms with them.
