Ada was a saint and abbess who lived during the late 6th or early 7th century. A member of the Catholic Church, she served as a nun in Soissons, France, before being elevated to the position of abbess. Her relative, Saint Englebert, who served as the bishop of Le Mans, supported her religious career by promoting her to leadership in Soissons and later transferring her to the monastery of Pré in Le Mans to serve as its abbess.
