Usual English spelling of the name of the first Christian martyr (Acts 6–7), whose feast is accordingly celebrated next after Christ's own (26 December). His name is derived from the Greek word stephanos ‘garland, crown’.
English and Scottish: patronymic from the personal name John. As an American family name, Johnson has absorbed patronymics and many other derivatives of this name in continental European languages. (For forms, see Hanks and Hodges 1988.)
