Juthwara's name is how she is known in Anglo-Saxon. Some have suggested that it is a corruption of the British Aud Wyry (meaning "Aud the Virgin"), the name by which she is known in Brittany. However, since Aud Wyry simply means "Aud the Virgin" (Aud is a Germanic name used in Northern France and not a Celtic name) it is more likely that Aud Wyry is a Breton reinterpretation of her original name. She was said to have been the sister of Paul Aurelian, Sidwell of Exeter and Wulvela but this is debated.
