Saint Roch was said to be a member of the house of la Croix de Castries, whichwas ennobled at the end of the 15th century.
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.
