Anglo-Saxon Chronicle. 626. This year came Eamer from Cwichelm, king of the West-Saxons, with a design to assassinate King Edwin (age 40); but he killed Lilla his thane, and Forthere, and wounded the king (age 40). The same night a daughter was born to Edwin (age 40), whose name was Eanfleda. Then promised the king to Paulinus, that he would devote his daughter to God, if he would procure at the hand of God, that he might destroy his enemy, who had sent the assassin to him. He then advanced against the West-Saxons with an army, felled on the spot five kings, and slew many of their men. This year Eanfleda, the daughter of King Edwin (age 40), was baptized, on the holy eve of Pentecost. And the king within twelve months was baptized, at Easter, with all his people. Easter was then on the twelfth of April. This was done at York [Map], where he had ordered a church to be built of timber, which was hallowed in the name of St. Peter. There the king gave the bishopric to Paulinus; and there he afterwards ordered a larger church to be built of stone. This year Penda began to reign; and reigned thirty winters. He had seen fifty winters when he began to reign. Penda was the son of Wybba, Wybba of Creoda, Creoda of Cynewald-, Cynewald of Cnebba-, Cnebba of Icel, Icel of Eomer, Eomer of Angelthew, Angelthew of Offa, Offa of Wearmund, Wearmund of Whitley, Whitley of Woden.

Anglo-Saxon Chronicle. 645. This year King Kenwal was driven from his dominion by King Penda.

Bede. 655. AD. How when King Penda was slain, the province of the Mercians received the faith of Christ, and Oswy (age 43) gave possessions and territories to God, for building monasteries, as a thank offering for the victory obtained.

At this time, King Oswy (age 43) was exposed to the cruel and intolerable invasions of Penda, king of the Mercians, whom we have so often mentioned, and who had slain his brother;⁴³¹ at length, compelled by his necessity, he promised to give him countless gifts and royal marks of honour greater than can be believed, to purchase peace; provided that he would return home, and cease to waste and utterly destroy the provinces of his kingdom. The pagan king refused to grant his request, for he had resolved to blot out and extirpate all his nation, from the highest to the lowest; whereupon King Oswy (age 43) had recourse to the protection of the Divine pity for deliverance from his barbarous and pitiless foe, and binding himself by a vow, said, "If the pagan will not accept our gifts, let us offer them to Him that will, the Lord our God."
