Marquis or marques is the second order in the peerage of England, ranking below a duke and above an earl. The title was originally applied to certain officers appointed to defend the marches or borders of Wales. The first marques proper was Robert de Vere, Earl of Oxford, who was created Marques of Dublin by Richard II in 1386. In 1397 Richard made John Beaufort, earl of Somerset, Marques of Dorset. The oldest existing marquisate is that of Winchester, dating from Edward VI in 1551. The eldest son of a marquis is generally by courtesy an earl, and the younger sons and the daughters are styled lords and ladies. His wife is a marchioness. Marquis is often the courtesy title of the eldest son of a duke during his father's lifetime. Research Marquis
