In his Life of Kentigern, Jocelin combined the lives of the northern Cyndeyrn Garthwys, that is Kentigern, with the southern Cyndeyrn ap Cyngar. As a result the story appears to state anachronisms. However, in reality, Kentigern of gen. 2 would have been a contemporary of Moken if he was Morgan Fwlch, one of Barturm’s candidates for the name. However, when the story shifts to the south with with Dewi in Menevia, Cadwallon Lawhir and Maelgwn Gwynedd the saint was Cyngar, not Kentigern. Finally, the Vita returns to the north with Kentigern and Rhydderch Hen.

Jocelin did not give the name of Kentigern’s father, perhaps, because of having to avoid choosing between Owain ab Urien and Cyngar ap Garthog. Cyndeyrn was probably the saint of Llangyndeyrn. Nothing is known about him as his story was absorbed into that of Kentigern.
