Aldegund was a 7th-century Frankish Benedictine abbess born in Cousolre. A member of the Merovingian royal family, she was the daughter of Count Walbert and Bertilla de Mareuil. Although she faced pressure to marry, she instead dedicated herself to religious life. She established a small hospital at Malbode on the banks of the Sambre, a site that eventually grew into the prominent Maubeuge Abbey. She is remembered as a central figure in the group of Merovingian saints known as the Maubeuge Cycle.
