From A History of Wales by John Davies, London, 2007, p. 83:

"If the intention of the rulers of Dyfed and Brycheiniog in seeking the patronage of Alfred was to remain free from the clutches of the house of Rhodri, they failed. About 904, Llywarch ap Hyfaidd, king of Dyfed, died; his kingdom came into the possession of Hywel ap Cadell ap Rhodri, the ruler of Seisyllwg and the husband of Elen, Llywarch's daughter. It would appear that Hywel also took possession of Brycheiniog, for its royal line ends with Tewdwr ap Griffri, who died about 930. The enlarged kingdom came to be known as Deheubarth, a unit of central importance in the history of Wales during the following four centuries.

"...Deheubarth was united with the territories of Idwal ab Anarawd ap Rhodri--Gwynedd and Powys--in 942, and Hywel died in 950 (or perhaps 949) the ruler of a kingdom which extended from Prestatyn to Pembroke."

Hywel married Elen ferch Llywarch, daughter of Llywarch ap Hyfaidd King of Dyfed and Unknown. (Elen ferch Llywarch was born about 885 in Dyfed, , Wales and died in 943.)
