Osric King Deira was born to Æthelric King Deira.
Bede. 633. AD. How King Edwin's next successors lost both the faith of their nation and the kingdom; but the most Christian King Oswald retrieved both.
Edwin (age 47) being slain in battle, the kingdom of the Deiri, to which province his family belonged, and where he first began to reign, passed to Osric, the son of his uncle Aelfric, who, through the preaching of Paulinus, had also received the mysteries of the faith. But the kingdom of the Bernicians-for into these two provinces the nation of the Northumbrians was formerly divided282-passed to Eanfrid (age 43), the son of Ethelfrid283, who derived his origin from the royal family of that province. For all the time that Edwin reigned, the sons of the aforesaid Ethelfrid, who had reigned before him, with many of the younger nobility, lived in banishment among the Scots or Picts, and were there instructed according to the doctrine of the Scots, and were renewed with the grace of Baptism. Upon the death of the king, their enemy, they were allowed to return home, and the aforesaid Eanfrid (age 43), as the eldest of them, became king of the Bernicians. Both those kings284, as soon as they obtained the government of their earthly kingdoms, abjured and betrayed the mysteries of the heavenly kingdom to which they had been admitted, and again delivered themselves up to defilement and perdition through the abominations of their former idolatry.

And to Bernicia succeeded Eanfrith (age 44), son of Ethelfrith. This year also Bishop Birinus first preached baptism to the West-Saxons, under King Cynegils. The said Birinus went thither by the command of Pope Honorius; and he was bishop there to the end of his life. Oswald (age 30) also this year succeeded to the government of the King Northumbrians, and reigned nine winters. The ninth year was assigned to him on account of the heathenism in which those lived who reigned that one year betwixt him and Edwin.

His body lies at Lichfield [Map]; but that of Ethelred, the son of Penda, at Bardney [Map]. Ethelbald then succeeded to the kingdom of Mercia, and held it one and forty winters. Ethelbald was the son of Alweo Iclingas, Alwy of Eawa, Eawa of Webba, whose genealogy is already written. The venerable Egbert (age 77) about this time converted the monks of Iona to the right faith, in the regulation of Easter, and the ecclesiastical tonsure.
Anglo-Saxon Chronicle. 827. This year was the moon eclipsed, on mid-winter's mass-night; and King Egbert (age 54), in the course of the same year, conquered the Mercian kingdom, and all that is south of the Humber, being the eighth king who was sovereign of all the British dominions. Ella, king of the South-Saxons, was the first who possessed so large a territory; the second was Ceawlin, king of the West-Saxons: the third was Ethelbert, King of Kent; the fourth was Redwald, king of the East-Angles; the fifth was Edwin, king of the Northumbrians; the sixth was Oswald, who succeeded him; the seventh was Oswy, the brother of Oswald; the eighth was Egbert, king of the West-Saxons (age 54). This same Egbert (age 54) led an army against the Northumbrians as far as Dore, where they met him, and offered terms of obedience and subjection, on the acceptance of which they returned home.
