Owain ab Edwin of Tegeingl

[1] The cantref formed the eastern part of Perfeddwlad (or Y Berfeddwlad) on the northern coast of Wales between the River Clwyd and Deeside.

[5] Owain's father, Edwin, appears to have been raised to the lordship of Tegeingl by Gruffydd ap Llywelyn,[3] ruler of most of Wales between 1055 and 1063.

[6] Links to previous rulers through the female line were very important in establishing a claim, and Owain's relationship with Bleddyn ap Cynfyn through his mother would have been relevant.

[6] In the 1080s and the 1090s, the Normans led by Hugh d'Avranches, 1st Earl of Chester made several attempts to invade and gain control of North Wales.

As a result of the intervention of a Norwegian army under Magnus Barelegs, the Normans suffered a defeat and withdrew most of their forces to England.

[1] However, in 1125 a son of Gruffudd ap Cynan killed all Owain's male heirs bringing the direct line of the family to an end.
