Baron Bruntisfield, of Boroughmuir in the City of Edinburgh, is a title in the Peerage of the United Kingdom. It was created in 1942 for the Scottish Conservative politician and former Vice-Chamberlain of the Household, Sir Victor Warrender, 8th Baronet. The Warrender family descends from George Warrender. He was Lord Provost of Edinburgh and represented Edinburgh in Parliament. In 1715 he was created a baronet, of Lochend in the County of Haddington, in the Baronetage of Great Britain.^[1] His grandson, the third Baronet, fought at the Battle of Minden in 1759, represented Haddington Burghs in the House of Commons and served as King's Remembrancer of the Court of Exchequer from 1771 to 1791. He was succeeded by his son, the fourth Baronet. He sat as a Member of Parliament for Haddington Burghs, Truro, Sandwich, Westbury and Honiton and notably served as a Lord of the Admiralty from 1812 to 1812. In 1822 Warrender was admitted to the Privy Council. On his death the title passed to his younger brother, the fifth Baronet. His grandson, the seventh Baronet, was a Vice Admiral in the Royal Navy. He was succeeded by his son, the eighth Baronet, who was raised to the peerage as Baron Bruntisfield, of Boroughmuir in the City of Edinburgh, in 1942. As of 2010 the titles are held by the latter's grandson, the third Baron, who succeeded in 2007. He is a retired officer in the British Army and investment banker.
