Resumen:
The ninth-century Historia Brittonum states that the first wife of Oswiu (d. 670) of Northumbria was Rhiainfellt, daughter of 'Royth', the son of Rhun. It states also that Rhun son of Urien baptised Edwin of Northumbria. That would have been in 627. But because neither fact is mentioned by Bede, historians have impugned both from Victorian times to the present. A survey of discussion hence tells us much of modern historians' attitudes; analysis of material suggests that the Welsh sources here tell a truth suppressed by Bede. The Welsh version would be confirmed by textual emendation of the name 'Royth', which is corrupt. It is surely Old Welsh Reyth, giving Rhaith 'right, justness' in today's Welsh, an appropriate name for a British cleric's son, as opposed to the ferociously warlike ones usually possessed by the early Celtic ruling class
