Pierre d'Arc

Pierre d'Arc was the son of Jacques d'Arc and the elder brother of the famous French saint and hero Joan of Arc. He had dark hair, swarthy complexion and was quick and lithe.

During their youth, Pierre often teased Joan due to her "strangeness". On 1 May 1428, the eldest Jean and Pierre met their step cousin, Gabriel Laxart, and gladly took the bread that their mother delivered through him. After sharing stories, Pierre asked him to share some of the food to their sister.
