[The sources that Bartrum cites for Trahaearn are: “Plant yr Arglwydd Rhys” 2b, copied about 1500 from a MS probably composed in the mid to late 1300s; Peniarth 128 (789b), “Llyfr Edward ap Roger”, written before 1582; and Peniarth 133 (170, 194), and Peniarth 176 (357), by Gruffudd Hiraethog (died 1564). Bartrum comments on “Plant yr Arglwydd Rhys” that it contains palpable errors and must be treated with caution. The relevant passage is: “Gwraic Gruffudd ap Ednyfed oedd Wenllian verch Howel ap Trahayarn ap Gwgan ap Bleddyn ap Maenyrch o Vrychainioc.”]
