Ælfthryth of Crowland

Ælfthryth, also known as Alfreda, Alfritha, Aelfnryth, or Etheldritha, is a Mercian princess, saint, virgin, and recluse, venerated in both the Catholic Church and Antiochian Orthodox Church. She was a daughter of King Offa of Mercia and his consort, Cynethryth.

Ælfthryth was "either betrothed to or loved by" Ælfthryth's sister Aelfreda also lost a husband due to their parents' political intrigue. Her tomb was arranged around St Guthlac's. A Crowland tradition states that Ælfthryth's relics were destroyed in 870 when Danes destroyed the abbey, but there is little evidence for it. Her feast day is 2 August.
