Family name is one that is shared with the family, but is not necessarily the surname. A good example to sum all this up would be the name of the main character of Kidnapped, David Balfour of the Shaws. His family name is the Shaws, but he is addressed as Mr. Balfour. His surname, in this case, is the same as his last name.

Two people can share a surname and have no biological relationship to each other.
