From Guy’s critical edition of the Llywelyn ab Iorwerth genealogies, which were based on an archetype created no later than the first half of the fourteenth century from an original compilation dating to the early thirteenth century, partly based on earlier written sources (Note that Guy is striving for textual rather than genealogical accuracy):
56. Llwyth Kollwyn:
