A History of Wales by John Davies, London, 2007, p. 81 has name as Llywarch ap Hyfaidd, in the line of Kings of Dyfed.

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."

Llywarch married.
