Everyone has family name..
The surname appears on the birth certificate.
For example, your father's or mother's name.
The family name matches old patronymic name, expression now deleted.
Last name is the same as birth name except in case of name change (for example, after a simple adoption or plenary, for legitimate reasons ...)
The usage name is used in everyday life.
