 In the early 660s, two important marriages took place.Ecgfrith of Northumbria, the fifteen-year-old son of Oswiu, married Æthelthryth of Ely, the daughter of Anna of East Anglia (who was about fourteen years older than him), and moved to live with him at his Northumbrian court.She had remained a virgin for Christ during her first marriage; she continued in this resolve as Ecgfrityh's bride, with the result that he could not expect to father an heir.
