Origin and Meaning of the Last Name Diaz
The last name Diaz has its roots firmly planted in Spanish-speaking countries, primarily Spain. It is traditionally a patronymic surname, meaning it originated from the name of a father or ancestor.
In this case, Diaz is derived from the given name Diego, which itself is a popular Spanish name with historical and religious connotations.
