Bertille of Thuringia

Saint Bertille of Thuringia ( (died 660 AD) or also known as Saint Bertilla, the daughter of Bercarius, King of Thuringia, was a Merovingian princess and Frankish saint who resided in the County of Hainaut in Belgium. Bertille was the mother of Saint Waltrude and Saint Aldegund, foundress of Maubeuge Abbey.

History Princess Bertille was born in the 7th century and was the daughter of Bercarius, King of Thuringia.

Her daughter Saint Waltrude was born in the 620s in Cousolre. She married Vincent Madelgarius and had four children: Aldetrude, Landry of Soignies, Madelberte of Maubeuge, and Dentelin of Mons. Her daughter Saint Aldegund established a convent of twelve Benedictine nuns near their tombs. When Saint Aldegund visited in 664 AD, she succumbed to cancer and was buried near her parents Bertille and Walbert. In 690 AD, her body was moved to Maubeuge Abbey by her niece, Saint Adeltrude, who succeeded her as abbess.

Bertille and her husband Walbert IV are both canonized. Their relics were preserved and placed at the Saint-Martin Church in Cousolre ( in 1661.

On her death, her daughter Saint Waltrude inherited the lands and titles, marrying Prince Madelgaire. Their son Landry (or Landric) and two daughters entered the Monastery of St. Aldegund, and after their son Dentelin's death, the duchy was left to their cousin Saint Aye, who devoted her inheritance to Saint Waltrude's church.
