Hiltrude of Liessies was an 8th-century French nun who sought a religious life despite her noble family's wishes. As the daughter of Wibert, Count of Poitiers, and the noblewoman Ada, she resisted a marriage to a Burgundian lord to follow her spiritual calling. With the support of the bishop of Cambrai, she entered the religious life, living in a cell near the abbey chapel founded by her father. Her decision to take the veil eventually inspired other noblewomen to join her, leading to the establishment of a female annex at the abbey.
