the Earl Marshal) be exempt from such a rule, in order to perform ceremonial functions. History of the office The office was originally held by Robert Malet, a son of one of the leading companions of William the Conqueror. In 1133, however, King Henry I declared Malet's estates and titles forfeit, and awarded the office of Lord Great Chamberlain to Aubrey de Vere, whose son was created Earl of Oxford. Thereafter, the Earls of Oxford held the title almost continuously until 1526, with a few intermissions due to the forfeiture of some Earls for treason. In 1526, however, the fourteenth Earl of Oxford died, leaving his aunts as his heirs. The earldom was inherited by a more distant heir-male, his second cousin. The Sovereign (at that time Henry VIII) then decreed that the office belonged to the Crown, and was not transmitted along with the earldom. The Sovereign appointed the fifteenth Earl to the office, but the appointment was deemed for life and was not hereditary. The family's association with the office was interrupted in 1540, when the fifteenth earl died and Thomas Cromwell, the King's chief adviser, was appointed Lord Great Chamberlain. After Cromwell's attainder and execution later the same year, the office passed through a few more court figures, until 1553, when it was passed back to the De Vere family, the sixteenth Earl of Oxford, again as an uninheritable life appointment. Later, Queen Mary I ruled that the Earls of Oxford were indeed entitled to the office of Lord Great Chamberlain on an hereditary basis. Thus, the sixteenth, seventeenth and eighteenth Earls of Oxford held the position on a hereditary basis until 1626, when the eighteenth Earl died, again leaving a distant relative as heir male, but a closer one as a female heir. The House of Lords eventually ruled that the office belonged to the heir general, Robert Bertie, 14th Baron Willoughby de Eresby, who later became Earl of Lindsey. The office remained vested in the Earls of Lindsey, who later became Dukes of Ancaster and Kesteven. In 1779, however, the fourth Duke of Ancaster and Kesteven died, leaving two sisters as female heirs, and an uncle as an heir male. The uncle became the fifth and last Duke, but the House of Lords ruled that the two sisters were jointly Lord Great Chamberlain and could appoint a Deputy to fulfil the functions of the office.
