 During the 640s, Hereswith's sister Hild received teaching from Saint Aidan of Lindisfarne.About 647, she travelled to the court of Anna to join her sister Hereswith in East Anglia.However, Hereswith had already left to live a religious life and as there was then no nunnery in her kingdom she travelled to Gaul and (according to Bede) lived at Chelles Abbey, where there was a royal oratory.
