Where the Mariani surname comes from
Mariani comes from the medieval name Mariano, Marianus in Latin. Originally it meant “of Mario,” but in the Middle Ages everyone read it as “of Mary.” The children of a Mariano became “the family of Mariano,” the Marianis. Scholars also point to a nickname given to families devoted to the Madonna.
