    "Though it was Owain who finally accepted the principle of Angevin overlordship over Gwynedd, he regarded himself as no ordinary vassal (his attitude to episcopal elections in the see of Bangor should be noted) and it is clear that it was he who gave initial direction to the policies of his successors. It was largely due to his example, moreover, that the native rulers of Wales ceased to be mere tribal chieftains and took their place alongside the great feudal magnates of the time. The praises so repeatedly accorded to his many personal qualities by contemporary poets, and indeed by several public figures who could not have been predisposed in his favour, have so genuine a tone about them that the progressive trends in all the arts of peace and war discerned in 12th century Wales, it must be concluded, were in large measure due to the fostering genius of 'Owain the Great.'"

    "It was part of the traditional lore of the Welsh bards that Gruffudd ap Cynan had made certain regulations to govern their craft, and his name was used to give authority to the 'statute' drawn up in connection with the Caerwys eisteddfod of 1523. There is nothing to substantiate this tradition, but it is not unreasonable to suggest that Gruffudd may have brought bards and musicians with him from Ireland and that these may have had some influence on the craft of poetry and music in Wales. He may also have made some formal changes in the bardic organization. It is clear that a genuine and persistent tradition to this effect existed in the 16th century. It is perhaps worth noting that the History mentions the death in battle of Gellan, Gruffudd's harpist, in 1094." [Dictionary of Welsh Biography, citation details below.]

    Of the identity of the mother of Gwladus ferch Llywarch, Stewart Baldwin (citation details below) notes: "Bartrum p. 354 gives Dyddgu ferch Iorwerth ap Cadwgan ab Elystan Glodrudd in this position, but his only source is the late visitation LD.ii.24, which names Dyddgu as the mother of another child of Llywarch, but not of Gwladus (#5). In addition, the sources given by Bartrum for Dyddgu's alleged father Iorwerth ap Cadwgan are all late 16th century or later, so Iorwerth's existence is also uncertain. In my opinion, this link should be regarded as dubious."
