Earl in 1641 the Earldom passed to his distant cousin John Manners of Haddon Hall, grandson of the second son of the first Earl. Dukedom of Rutland In 1703, the ninth Earl of Rutland was created Duke of Rutland and Marquess of Granby by Queen Anne. Marquess of Granby The most notable Marquess of Granby was John Manners (1721–1770), eldest son of the third Duke. He was an accomplished soldier and highly popular figure of his time; in 1745 he became a colonel; his military career flourished during the Seven Years' War. At the Battle of Minden (1 August 1759), although his role was small, he commanded the reserve cavalry. In 1760, at the Battle of Warburg, he led a cavalry charge which routed the French, losing his hat and wig in the process. In recognition of this, soldiers of the Blues and Royals (his former regiment) have the unique privilege in the British Army of being permitted to salute while not wearing headgear. Granby's losing his helmet and wig in the charge gave rise to the expression 'going bald-headed' at something. In 1758, the King made him Colonel of the Royal Horse Guards and in 1766, as Lieutenant-General, he became Commander-in-Chief (a basically political appointment). His title was honoured by being used by a large number of pubs throughout Britain, although the reason is little known. As Colonel, he provided for his most capable soldiers such that when they could no longer be of service to the Regiment, he would give them financial support to start a pub, the sole condition being that the pub was to be named "The Marquis of Granby" after him. The towns of Granby, Quebec in Canada and Granby, Massachusetts and Granby, Connecticut in the United States as well as Granby Street in Norfolk, Virginia, USA were also named after him. so too were two forts, Fort Granby, in Tobago, and Fort Granby in South Carolina. He died before his father, and therefore did not become Duke. Subsidiary titles The subsidiary titles of the dukedom are: Marquess of Granby (created 1703), Earl of Rutland (1525), Baron Manners, of Haddon in the County of Derby (1679), and Baron Roos of Belvoir, of Belvoir in the County of Leicester (1896).
