Passage: Lyfing's uncle was Burhweald, Bishop of Cornwall, according to the medieval chronicler William of Malmesbury. He was probably a monk either at Winchester Abbey or at Glastonbury Abbey. In 1009, he became Abbot of Tavistock, and that was always his favourite of the offices he held. In 1027, he became the Bishop of Crediton, and about the same time he became Bishop of Cornwall on the death of his uncle Brihtwold, so he united those two sees, with the seat at Crediton. His elevation probably was due both to his family and to his assistance to Cnut in Rome. There is also some indication he may have been a protege of Godwin, Earl of Wessex.
