and James. Jewish, Jacob; French, Jacques, our “Jack,” and Jacquemes, our “James.” Jacques used to be the
commonest name of France, hence the insurrection of the common people
was termed the insurrection of the Jacques, or the Jacquerie; and a rustic used to be called a Jacques bon homme. The Scotch
call Jack Jock.
