Canterbury ensured that the church in East Anglia adhered to Roman norms. Around 633, Sigeberht welcomed from Ireland, Fursey and his brothers Foillan and Ultan and gave them land to establish an abbey at Cnobheresburg. Felix and Fursey effected a number of conversions and established many churches in Sigeberht's kingdom. Around the same time Sigeberht established a monastery at Beodricesworth. Hilda of Whitby was the grand-niece of Edwin of Northumbria. In 627 Edwin and his household were baptized Christian. When Edwin was killed in the Battle of Hatfield Chase, the widowed Queen Æthelburh, her children, and Hilda returned to Kent, now ruled by Æthelburh's brother, Eadbald of Kent. Æthelburh established Lyminge Abbey, one of the first religious houses to be founded in the new Anglo-Saxon kingdoms. It was a double monastery, built on Roman ruins. Æthelburh was the first abbess. It is assumed that Hilda remained with the Queen-Abbess. Nothing further is known of Hild until around 647 when having decided not to join her older sister Hereswith at Chelles Abbey in Gaul, Hild returned north. (Chelles had been founded by Bathild, the Anglo-Saxon queen consort of Clovis II.) Hild settled on a small parcel of land near the mouth of the river Ware, where under the direction of Aidan of Lindisfarne, she took up religious life. In 649, he appointed her abbess of the double monastery of Hartlepool Abbey, previously founded by the Irish recluse Hieu. In 655, in thanksgiving for his victory over Penda of Mercia at the Battle of the Winwæd, King Oswiu brought his year old daughter Ælfflæd to his kinswoman Hilda to be brought up at the abbey. (Hild was the grand-niece of Edwin of Northumbria; Oswiu was the son of Edwin's sister Acha.) Two years later, Oswiu established a double monastery at Streoneshalh, (later known as Whitby), and appointed Hild abbess. Ælfflæd then grew up there. The abbey became the leading royal nunnery of the kingdom of Deira, a centre of learning, and burial-place of the royal family. Resolving blood feuds Eormenred of Kent was the son of King Eadbald and grandson of King Æthelberht of Kent. Upon the death of his father, his brother Eorcenberht became king. The description of Eormenred as king may indicate that he ruled jointly with his brother or, alternatively, that as sub-king in a particular area. Upon his death, his two young sons were entrusted to the care
