When Eadwine entered into a marriage alliance with the Kentish royal family, he gained a wife, Æthelburh, who was a practicing Christian. Paulinus, Æthelburh’s chaplain, was keen to convert the Northumbrian king and, after much prevaricating, Eadwine agreed to be baptized, along with his nobles, in the church of St Peter in York.
