Claim: The Catholic saint Saint Roch was said to be a member of the house of la Croix de Castries, which was ennobled at the end of the 15th century.
Evidence: Family tradition holds that one of the family's members was saint Roch, the pilgrim apostle who dedicated his life to the service of the sick and plague-victims in the 13th century. The La Croix de Castries family, however, was not ennobled until the end of the 15th century, as Nobles of the Sword.
