Aderald was a 10th-century priest and archdeacon from Troyes, France. Educated by religious scholars, he served as an acolyte under Bishop Manasses of Montdidier before entering the priesthood. He was widely recognized for his dedication to assisting the sick and the impoverished. Following a pilgrimage to the Holy Land, he established a priory in the village of Villacerf, which was later renamed Saint-Sépulcre, using a relic he brought from the Church of the Holy Sepulchre.
