Saint Cuthbert was a 6th-century hermit who became the bishop of Lindisfarne, an island off the coast of England. He was known as performer of healing miracles. Because of the saint, this name remained in use in England even after the
Norman conquest. It became rare after the
Protestant Reformation, but it was (briefly) revived in the 19th century.
