Relationships
(possible) Father: Gruffudd ap Llywelyn Fawr ab Iorwerth Drwyndwn.
This relationship is shown by Bartrum (Gruffudd ap Cynfyn 5). Catrin is not mentioned by Pierce. Beverley Smith (p. 39 fn) notes that Catrin's existence is not recorded except in genealogies.
(possible) Mother: Rhanullt, daughter of Ragnvald Godredsson, king of the Isles.
This relationship is shown by Bartrum (Gruffudd ap Cynfyn 5). The reliability of the late sources Bartrum is using is unclear, as they seem unaware of another of Gruffudd’s wives (Senena). Beverley Smith (p. 39 fn) notes that there is no reference to Catrin in record sources outside the genealogies, and he expresses some doubt (pp. 37-38) about the reality of Rhanullt's relationship with Gruffudd.
Spouse: Iorwerth Fychan ab Yr Hȇn Iorwerth ab Owain.
This relationship is shown by Bartrum (Gruffudd ap Cynfyn 5).
Spouse: Maredudd ap Madog ap Gruffudd Maelor.
