Son of Tewdwr ap Cadell, another descendant of Hywel Dda, made himself master of Deheubarth after Rhys ab Owain's death in 1078. He married Gwladus, daughter of Rhiwallon ap Cynfyn, and had issue Gruffydd, Hywel, and Nest. His immediate task was to hold at bay Caradoc, who had slain his two predecessors. Temporarily dispossessed by his adversary in 1081, he joined forces with Gruffydd ap Cynan of Gwynedd to defeat and kill Caradoc at Mynydd Carn. He came to terms with William ‘the Conqueror’ and did homage, but remained under attack from rival Welsh princes. In April 1093 he was killed near Brecon in circumstances which are not clear, probably attempting to resist the Norman advance up the Usk valley.
