Aderald

Aderald (died 1004) was a canon and archdeacon of Troyes, France, from where he led a pilgrimage to the Holy Land. He brought back a piece of the Holy Sepulchre, and founded a monastery named after it—Saint-Sépulcre—in Villacerf. He was canonized as a saint of the Catholic Church; his feast day is on October 20. He is also venerated as a saint in the Eastern Orthodox Church.
