Elder son of Owain Gwynedd by Gwladus, daughter of Llywarch ap Trahaearn. He married a princess of Powys, namely Marared, daughter of Madog ap Maredudd, by whom he had one son, the future Llywelyn ap Iorwerth. In the partition of his father's territories he received Arfon and probably Nanconwy. Shortly afterwards he disappears from view, probably dying about the time of the usurpation of power in Upper Gwynedd by his half-brother, David I, in 1174.
