Family:Gruffydd Ap Madog Vychan and Elizabeth Strange (1)

The said Griffith ap Madoc, Lord of Glyndyfrydwy and Cynllaeth, was Steward of Oswestry under Richard FitzAlan, Earl of Arundel in 1347 (Mr. J. Morris' MS.) He was married to Elizabeth, daughter of John, Lord Strange of Knockin, by his wife Maud daughter of Roger d'Eiville, at Rhuddallt, on the quinzaine of the Nativity of St. John the Baptist, (July 8) 1304 (vide King's writ to the Bishop of St. Asaph and return thereto, anno 11 Edw. II, taken from the Red Book of St. Asaph by Mr. Robert Vaughan of Hengwrt, ex inf. Mr. J. Morris).

also:

Sir John l'Estrange, Lord of Knockin, bought for his daughter Elizabeth, from Madoc ap Griffith, the marriage of the said Griffith, his son and heir, for which he paid £50 sterling (Rot. Parl. Vol. I, p. 306).

Gruffydd Vychan's son Madog died on November 12, 1304, and his son, the Griffith who married Elizabeth le Strange, was born in 1298 so that he was only six years old at the time of his marriage. Clearly, le Strange took advantage of his position to secure more Welsh lands for his family. A petition of Maud, widow of John le Strange (V), made in the 8th of Edward II, when she was wife of Thomas Hastang [Rot. Parl. 306.], shows that they bought the marriage from Madog, at a cost of £50, paid in advance. After Madog died, le Strange continue to act as keeper of his son-in-law's lands until his own death. The husband of Elizabeth was certainly grandfather of Owen Glendower, and no other marriage of his is on record. That Glyndyvrdwy was entailed on their heirs is borne out by a settlement therof [Rot. Parl. iv. 440.] made to a Griffith of Glyndyvrdwy, great-grandfather of Owen Glyndwr's daughter Alice, and to a certain Elizabeth his wife, and to their heirs. It was thus, through the le Strange marriage, that Glyndwr's estates were continued to his successors.
