Name also spelled Kyneburg (a) or Cyniburg; Benedictine abbess, one of the remarkable progeny of Penda, pagan king of Mercia, all zealous propagators of the faith among whom are several saints; d. c. 680. Before 653 she married Alcfrith, son of King Oswy of Northumbria, himself sub-King of Deira. Probably upon his death, after 664, or possibly, as Florence of Worcester says, "renouncing a marriage of fleshly connection for love of God," she became abbess of the house called after her, Cyneburgecaestre, now Castor, Northamptonshire (where there is still a path called Lady Connyburrow's Way). A doubtful peterborough tradition records her participation in the original endowment of that abbey. In the mid-tenth century her remains were translated there from Castor. Her name occurs with Alcfrith's in runic on the Bewcastle Cross.
Feast: March 6.
