Madalberta

Madalberta was the daughter of Saints Vincent Madelgarus and Waldetrudis. She was brought up by her aunt, Saint Aldegund, the founder of Maubeuge, where she became a nun. Around 697 she succeeded her sister, Saint Aldetrudis, as abbess. She reposed in the year 706. She is a saint of the undivided Church, venerated in the West.

Her commemoration falls on 7 September (new calendar); the Churches on the Old Calendar keep the same day of the Menaion on 20 September of the civil calendar.
