a 'dependant barony' of the lordship of Glamorgan and the hilly district bounded by Brecknock on the north, Cefn Onn ridge on the south, the river Taff on the west and the river Rhymney on the east.
In 1158 he attacked and slew Morgan ab Owain of Gwynllwg and Caerleon, together with 'the best poet,' Gwrgant ap Rhys. He is noteworthy also for his attack on Cardiff castle the same year, when at dead of night he removed William, earl of Gloucester, Hawise his wife, and Robert their son to his wooded fastnesses, refusing to release them until William had restored the lands filched from him and had bestowed upon him additional territory by way of compensation.
He married Nest, sister says ' Brut y Saeson,' to the 'lord' Rhys. He was succeeded (before 1170) by his son Gruffydd.
