Relationships
Father: Caradog.
Bartrum (EVWG Early Series [46]) shows a string of ancestors for Caradog, but Baldwin (LaI) notes that it is not clear that they are historical. The father of Trahaearn is recorded as Caradog in Brut y Tywysogion s.a.1073, and s.a. 1079, and in Annales Cambriæ s.a. 1073.
Mother: unknown.
Baldwin (LaI) notes that there has been speculation that she was a sister of Cynfyn ap Gwerystan, but that there are other possible interpretations of the evidence. Maund (1991, p. 82) makes a similar point.
Spouse: uncertain.
Bartrum (EVWG Trahaearn ap Caradog 1) shows Nest ferch Gruffudd ap Llywelyn, but Baldwin (LaI) regards this as dubious.

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):
