Events
Date of Birth: about 1010.
This estimated date is given by Bartrum (EVWG [42], Tewdwr Mawr).
Date of Death: unknown.
According to Brut y Tywysogion (Williams pp. 50-51) and Annales Cambriæ (Williams p. 27), Tewdwr’s son Rhys began his reign in 1077. Lloyd/Thornton corrects this to 1079. Tewdwr presumably was dead by then.
Relationships
Father: Cadell ab Einion ab Owain.
This relationship is shown by Bartrum (EVWG [42], Tewdwr Mawr; EWGT) and given by Lloyd/Thornton. It is given by Giraldus Cambrensis (Description of Wales 1:167). Some sources omit Cadell from the name string, making Tewdwr the son of Einion, but this raises chronological problems.
Mother: Elinor ferch Gwerystan.
This relationship is shown by Bartrum (EVWG [42]).
Spouse: unknown.
