Hywel ab Owain Gwynedd

[3][4][5] Hywel and Cadell ap Gruffydd of Deheubarth joined forces against the Normans in West Wales, they took Carmarthen, Llansteffan, and Wiston castles.

[3] In 1146, news reached King Owain Gwynedd that his favoured eldest son and heir (Edling), Rhun, died.

[4][hyw 4] As the eldest surviving son and Edling, Hywel succeeded his father in 1170 as King of Gwynedd in accordance with Welsh law and custom.

Within months of his succession, Hywel was forced to flee to Ireland, returning later that year with a Hiberno-Norse army and landing on Môn, where he may have had Maelgwn's support.

Iorwerth was apportioned the commotes of Arfon and Arllechwedd, with his seat at Dolwyddelan, with Maelgwn retaining Ynys Môn, and with Cynan receiving Meirionnydd.

[9] Hywel ab Owain is also written about in Sharon Kay Penman's novels When Christ and His Saints Slept, and Time and Chance.

Prince Hywel ab Owain is also a major character in Sarah Woodbury's book series The Gareth & Gwen Medieval Mysteries.
