Hywel succeeded to the estates of his father in 1457/8. He supported Lancaster in the Wars of the Roses. Jasper Tudor sought refuge with Hywel at Mostyn in 1464. Mostyn (pp. 56-66) states that contemporary poetry about Hywel by Gutto’r Glyn survives, but Carr (1975, p. 45) states that these were about another Hywel ab Ieuan Fychan.
Events
Date of Birth: unknown.
Place of Birth: unknown.
Date of Death: by 1479.
Carr (1979, p. 157) states that Hywel probably predeceased his father (who died in 1477) and was certainly dead by 1479. Mostyn (p. 59) states that Hywel “died young, perhaps in 1468 from a wound received during the rout of Jasper Tudor’s forces by Richard Herbert, after the siege of Denbigh.” Carr (1975, p. 44) notes that Hywel was certainly still alive in September 1469, when he witnessed a deed.
Relationships
Father: Ieuan Fychan ab Ieuan ab Adda.
This relationship is given by Mostyn (p. 56), by Dwnn (2:308), by Lloyd (4:146-147), by Glenn (p. 144), by Carr (1979, p. 138, p. 157), and by Davies. It is shown by Bartrum (Tudur Trefor 13 (C1)).
Mother: Angharad ferch Hywel ap Tudur.
This relationship is given by Mostyn (p. 56), by Dwnn (2:308), by Lloyd (4:146-147), by Glenn (p. 144), by Carr (1979, p. 138, p. 157), and by Davies. It is shown by Bartrum (Tudur Trefor 13 (C1)).
Spouse: Margred ferch Gruffudd ap Rhys (died 1532).
This relationship is given by Mostyn (p. 60), by Dwnn (2:308), by Lloyd (4:147), by Carr (1979, p. 138, p. 139), and by Davies. It is shown by Bartrum (Tudur Trefor 13 (C2)). Mostyn (p. 60) gives the date as 1458, arguing that the 1460 date usually given is an error due to a misreading of a 1663 MS. pedigree. Carr (1975, p. 44) states that either 1458 or 1460 is too early a date.
Concubine: Angharad ferch Llywelyn ap Deiws ap Dafydd.
This relationship is shown by Bartrum (Tudur Trefor 13 (C2)).
