Earl Jellicoe is a title in the Peerage of the United Kingdom. It was created, along with the subsidiary title Viscount Brocas, of Southampton in the County of Southampton, on 29 June 1925 for Admiral of the Fleet John Jellicoe, 1st Viscount Jellicoe, on his return from being Governor-General of New Zealand, with remainder to the heirs male of his body. He had already been created Viscount Jellicoe, of Scapa in the County of Orkney, on 15 January 1918, created with remainder to the heirs male of his body, and in default of such issue to his eldest daughter and the heirs male of her body, with the like remainder in default of such issue to every other daughter successively in order of priority of birth, and to the heirs male of their bodies. The Viscountcy was created with remainder to his daughters and their heirs male because, at the time of the creation, Jellicoe had five daughters and no sons. His only son was born three months later.
The Viscountcy Brocas is used as a courtesy title for the Earl's eldest son and heir apparent. Brocas was chosen due to the descent of Admiral Jellicoe's great-grandmother, Jane Elizabeth, daughter of Sir James Whalley-Smythe-Gardiner, 2nd Baronet, of Roche Court, Fareham, from the last of the Brocases of Beaurepaire (purchased 1353, sold 1873), Sherborne St John, Hampshire. This was a family with Gascon roots that produced two Masters of the Horse and a 300-year (14th to 17th century) line of hereditary Masters of the King's Buckhounds.
Earl Jellicoe was succeeded by his only son, George Patrick John Rushworth Jellicoe. The second earl served in the Coldstream Guards, No. 8 Commando, the Special Air Service and commanded the Special Boat Service during the Second World War. He later became a diplomat and a Conservative politician and served as the last First Lord of the Admiralty from 1963 to 1964 and as Lord Privy Seal and Leader of the House of Lords from 1970 to 1973. In 1999 he was given a life peerage as Baron Jellicoe of Southampton, of Southampton, in the County of Hampshire, and remained a member of the House of Lords despite the passing of the House of Lords Act 1999 which removed the hereditary peerage's automatic right to sit in the Lords. Until his death in 2007, the second Earl Jellicoe was the longest-serving member of the Lords, and technically the longest-serving parliamentarian in the world, having taken his seat in 1939.
