Relationships
Father: Gronwy.
Bartrum (Edwin 1) shows and Thornton gives Edwin’s father as Gronwy. Maund (p. 51) notes that Uchdrud's father is named as Edwin ap Goronwy in the Brutiau s.a. 1115. Lloyd (ii, 407, n. 33) comments: "Uchtryd and his brother Owain are said to have been the sons of Edwin ap Gronw ab Einion ab Owain ap Hywel Dda, an unattested but not an impossible pedigree." Carr (p. 61) states that Edwin was a great-great-grandson of Hywel Dda.
Mother: unknown.
Davies gives Ethelfleda, daughter of Edwin, "king of Mercia". There was no Edwin, king of Mercia, although there was an earl Edwin. I am not sure on what evidence any connection to Edwin of Tegeingl is based on.
Spouse: Iwerydd ferch Cynfyn.
This relationship is shown by Bartrum (Edwin 1) and by Davies.
