In 625, the widowed Edwin married the Christian princess Æthelburh of Kent, daughter of King Æthelberht of Kent and the Merovingian princess Bertha of Kent. As part of the marriage contract, Aethelburh was allowed to continue her Roman Christian worship and was accompanied to Northumbria with her chaplain, Paulinus of York, a Roman monk sent to England in 601 to assist Augustine of Canterbury. Augustine's mission in England was based in Kent, and is referred to as the Gregorian mission after the pope who sent him. As queen, Æthelburh continued to practice her Christianity and no doubt influenced her husband's thinking as her mother Bertha had influenced her father.
