Nest had borne Owain two sons, Llywelyn and Einion, before eventually being returned to her husband Gerald of Windsor.

Owain returns with the Henry in 1115 and in 1116 takes to arms to assist the king in putting down the rebellion of Gruffydd ap Rhys of Deheubarth.

Gerald, who is fighting on the same side, takes the opportunity for vengeance, attacking Owain when he has only ninety men with him and killing him.

Most of Powys now passes to his uncle, Maredudd.
