Saint Kyneburgha (- c.680)

She was the eldest daughter of Penda, the pagan King of Mercia. She married King Ealhfrith, co-regent of Northumbria, but later left him and established an abbey at Castor, near Peterborough, of which she became the first abbess. She was buried in her church: her remains were later removed to the abbey in Peterborough, where she was venerated as a saint by the monastic community.
