Owain ab Edwin of Tegeingl

Owain ab Edwin of Tegeingl or Owain the Traitor, (died 1105) was lord of the cantref of Tegeingl in north-east Wales at the end of the 11th century. He was the son of Edwin ap Gronw of Tegeingl, a great-great-grandson of Hywel Dda. He sided with the Normans in their failed invasion of North Wales, and in the 1090s attempted to become ruler of Gwynedd. His arms were gules three men's legs conjoined at the thighs in triangle argent. Ancestry Little is known of Owain's father, Edwin of Tegeingl. However, most medieval pedigrees identify Owain's paternal grandfather as Gronwy, a descendant of Hywel Dda. Owain may have been a great-great-great-grandson of Hywel Dda although this is disputed. His paternal grandmother is believed to have been Ethelfleda or Aldgyth, daughter of Eadwine of Mercia. His mother was Iwerydd, sister of Bleddyn ap Cynfyn, Prince of Gwynedd and Powys (1063–1075).
