Commentary
The traditional construction makes the Madog of this page “Madog Fychan”, and makes him the son of Madog Crupl (died about 1304) and Margred ferch Rhys Ieuanc. Bartrum originally gave this (Bleddyn ap Cynfyn 4). Lloyd (p. 12 fn 4) argued that Madog Fychan and Madog Crupl were the same person: “The evidence makes it quite certain that there was only one Madog in the Glyn Dyfrdwy pedigree; probably ‘Madog Grupl’ (the cripple), as found in many genealogies, is an alias of Madog ap Gruffydd and points to some constitutional weakness.” Bartrum later came to agree with this, citing CIPM volume 6, no. 128, which seems to settle the issue. Bartrum suggests that Margred and Gwenllian may both have been wives of the one Madog.
Bollard (p. 426) still expresses some doubt about the identification, as the use of the appellative “Fychan” was unusual in the early 1300s when a son was not named after his father. However, Lloyd (p. 13 fn 2) cites Rot. Parl. i. 306 (nos. 74 and 75), which explicitly name Madog “Maddoc Vaghan ap Griffith.”
