She was sister to Saint Guthlack, the famous hermit of Croyland, and though of the royal blood of the Mercian kings, forsook the world, and led an austere retired life in the country which afterwards bore her name, in Northamptonshire, at a distance from her holy brother. Some time after his death she went to Rome, and there slept in the Lord, about the year 719. Ordericus Vitalis says, her relics were honoured with miracles, and kept in a church which bore her name at Rome; but this church is not now known. From one in Northamptonshire, a village still retains the name of Peagkirk, vulgarly Pequirk; she was also titular saint of a church and monastery in Pegeland, which Saint Edward the Confessor united to Croyland. She is called Saint Pee in Northamptonshire, and Saint Pege at Croyland.
