Hildegard of the Vinzgau (b. 758)
Hildegard (c. 754 – 30 April 783), was a Frankish queen consort who was the second wife of Charlemagne and mother of Louis the Pious. Little is known about her life, because, like all women related to Charlemagne, she became notable only from a political background, recording her parentage, wedding, death, and her role as a mother.
