Æthelthryth, English saint (b. 636)
Æthelthryth (or Æðelþryð or Æþelðryþe; c. 636 – 23 June 679 AD) was an East Anglian princess, a Fenland and Northumbrian queen and Abbess of Ely. She is an Anglo-Saxon saint, and is also known as Etheldreda or Audrey, especially in religious contexts. Her father was King Anna of East Anglia, and her siblings were Wendreda and Seaxburh of Ely, both of whom eventually retired from secular life and founded abbeys.
