NICKNAMES CAN, OF COURSE, spring up anywhere, anytime and in any place. They have always flourished best in rural communities where everyone knows his neighbors more intimately than is possible in urban centers. It is not at all unusual for one visiting the countryside in Europe and, for that matter, even in the United States, to find that numerous individuals or families actually have three names a given name, a last name and a nickname.
