Sir Gruffudd was an important supporter of Edward I and Edward II in North Wales. He is traditionally described as hero of a Welsh revolt in 1322, but the action was in fact supporting Edward II against Roger Mortimer (Edwards Welsh Biography).
Events
Date of Birth: unknown.
Place of Birth: unknown.
Edwards (p. 597) states that “at most Gruffydd can only have been a very small child at Henry III’s death.”
Date of Death: shortly before 12 July 1335.
Place of Death: unknown.
The date is given by Edwards. Gruffudd was still alive at the end of May in 1335. 12 July is the date of the writ for the inquisition post mortem.
Relationships
Father: Rhys ap Gruffudd ab Ednyfed Fychan.
This relationship is shown by Bartrum (Marchudd 17), and given by Edwards (EHR xxx, p. 589, citing contemporary documents), by Roberts (p. 274), by Carr (p. 141), and by Bridgeman (p. 232 fn).
Mother: Margaret, daughter of John le Strange.
This relationship is shown by Bartrum (Marchudd 17), and given by Edwards and by Bridgeman (p. 232 fn). Bridgeman (p. 231 fn) cites a charter dated at Caernarvon on April 20, 1284, in which “King Edward I concedes to Margaret, widow of Res ap Griffith ap Ednevet Vechan and daughter of John l’Estrange, for the term of her life, the whole Lordship of the Vill of Trefgarned, which had been settled on her by her late husband at the time of her marriage.”
(supposed) Spouse: Gwenllian ferch Cynan ap Maredudd.
This relationship is shown by Bartrum (Marchudd 17), citing later heraldic pedigrees. It is also given by Edwards, by Carr (p. 142), and by Bridgeman (p. 232 fn). Bridgeman (p. 221) states that he considers the marriage to be “somewhat problematical”.
