Edwin of Tegeingl
Later pedigrees provide Edwin and his descendants with a Welsh pedigree, making him son of Gronwy and great-great-grandson of Hywel Dda. However, it has been suggested that this pedigree may have been a late invention, and that his name points to an Anglo-Saxon origin. Edwin was Lord or Prince of the cantref of Tegeingl. The cantref formed the eastern part of Perfeddwlad (or Y Berfeddwlad) on the northern coast of Wales between the River Clwyd and Deeside. The territory, originally forming part of the Kingdom of Gwynedd, had been under the control of the Anglo-Saxons for several centuries and then changed hands several times between the two.
Edwin would come to be regarded as founder of one of the Fifteen Tribes of Wales, and as such antiquarians in later centuries would invent attributed arms for him. He had three sons, Owain, Uchdryd, and Hywel.
