According to a report by "Florence of Worcester", writing long afterwards, at some time before Aldfrith's death in 705 he and Cuthburh "renounced connubial intercourse for the love of God." Following this, Cuthburh entered Abbess Hildelith's nunnery at Barking Abbey. The dedication of Aldhelm's treatise De virginitate includes Cuthburh, who was then at Barking; it is thought that she was in some way related to Aldhelm.
She is described as austere, and she communicated with prelates through a little hatch in the nunnery at Wimborne. Among Saint Boniface's surviving letters is an anonymous account of a vision of Abbess Cuthburh in hell. The feast day associated with her is August 31.
