Note 1407 — Chapter X · THE REIGN OF EADWARD FROM THE DEATH OF THE ÆTHELING TO THE DEATH OF THE KING.[1258] 1057–1066.
Reading edition
The Worcester Chronicle (1063) says expressly that the two princes were Gruffydd’s brothers; “And se kyng Eadward betæhte þæt land his twam gebroþran Bleþgente and Rigwatlan.” In the two Welsh Chronicles no notice is taken of this investiture of Gruffydd’s successors, but in 1068 we find Bleddyn and Rhiwallon reigning; they are however called sons of Cynfyn, and are described as waging war with the sons of Gruffydd. Of Bleddyn we have heard before in the invasion of Herefordshire. See above, p. 388.
