Hedwig of Bavaria

Hedwig also Heilwig,[1] (c. 778 – c. 835) was a Saxon noblewoman, abbess of Chelles,[1] the wife of Count Welf, and mother-in-law of Emperor Louis the Pious through his marriage to Judith, her daughter.

[2] Hedwig was possibly born at Altdorf in the Frankish lands of Alamannia (present-day Germany).

Hedwig was ordained the abbess of Chelles before 825, likely entering upon Welf's death.

[4]Hedwig died in c. 835 and was buried in the Basilica of Saint Martin, in modern-day Baden-Wurttemberg.

Hedwig had a sister, Adalung des Franken; half-brother, Hunfrid I, Margrave of Istria; and a brother, Guelph, Count of Andechs.
