Hilda's elder sister, Hereswith, married Ethelric, brother of King Anna of East Anglia, who with all of his daughters became renowned for their Christian virtues. Later, Hereswith became a nun at Chelles Abbey in Gaul (modern France). Bede resumes Hilda's story at a point when she was about to join her widowed sister at Chelles Abbey. At the age of 33, Hilda decided instead to answer the call of Bishop Aidan of Lindisfarne and returned to Northumbria to live as a nun.
