Short form of Eugene, now used as a boy's given name in its own right, especially in North America. It has been made familiar by film actors such as Gene Autry, Gene Hackman, Gene Kelly, and Gene Wilder. It is also occasionally used as a girl's name, in which case it represents a respelling of Jean.
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.)
