The sources Bartrum gives for Owain are:

Achau Brenhinoedd a Thywysogion Cymru (probably based on 15th century MSS):

2a. [Plant Ywein Gwynedd]: “Iorwerth a Maelgwn a Gwenlliant, mam Wenwynwyn ap Owain Kyveiliawg, plant Owain Gwynedd.”

8g. “Gwenwynwyn ap Ywain Kyveilioc ap Gruffudd ap Meredudd ap Bleddyn ap Kynvyn ap Gwerystan ap Gweithfoet ap Gwny ap Gwlydden ap Gwrydyr ap Karadawg… I vam oedd Wenllian verch Ywain Gwynedd ap Gruffudd ap Kynan ap Iago...”

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):

12 Plant Ywain Gwyned:

12.1 Iorwerth a Maelgwn a Gwenlliant mam Wenwynwyn ap Ywain Kyfeiliawg, plant Ywain Gwyned, a Gwladus oed eu man, ferch Llewarch ap Trehayarn ap Karadawg ap Gwynn ap Gollwyn ap Ednywain ap Bledynt ap Bledrus ap Kynawg Mawr ap Iorwerth Hirvlawt ap Tegonwy ap Teon
