Is that you cousin Jack? Jack and Jill represent Louis XVI of France, who was deposed and beheaded in 1793 (lost his crown), and his Queen Marie Antoinette (who came tumbling after) albeit the fact that the earliest printing of the rhyme pre-dates those events. In any event, John Nance Garner III (November 22, 1868 – November 7, 1967), known among his contemporaries as "Cactus Jack", was an American Democratic politician and lawyer from Texas. Thank you kindly, don't mind if I do.
