560AD. At the death of Ida of Bernicia, Aelle seized the Bernician lands below the river Tees.
580AD.The army of Peredyr and Gwrgi of the british kingdom of Ebrauc marched north to fight the Angles of the north. They were both slain when they came against the forces of (king Adda?) at Caer Greu. It was more likely to have been the forces of king Aelle they met, since Adda had been dead for many years by then. Eubrauc was based around York and any army raised there would have been at threat to Deira. In fact the Deirians rose up under Aelle, moved on the city of Ebrauc and King Peredyr’s son was forced to flee the kingdom.
One of Aelle’s sons was Edwin who became king of Northumbria and his daughter married Æthelfrith of Bernica.
