Oswiu of Northumbria
About 634 Oswiu married Rhiainmelt, daughter of Rhoeth of Rheged, a marriage alliance arranged by his brother King Oswald. He had a son by this marriage, Alfrith of Deira. Rhiainmelt seems to have died as a year later Oswiu was in Ireland with the Dál Riatans. There he was involved with Fina, the daughter of the high King Colman. There is no record they married but they had a son Aldfrith of Northumbria (Irish name Flann Fína mac Oswiu).
