About
Cadell ap Rhodri (d.909), King of Seisyllwg, was a younger son of Rhodri the Great who secured the southern share of his father's realm. History remembers him chiefly for his son: Hywel Dda, 'Hywel the Good', the king whose name is on the medieval laws of Wales. Through Cadell the southern royal line of Deheubarth descends; and with it a strand of this family.
