The Bentinck family is a prominent family belonging to Dutch, German and British nobility. Its members have served in the armed forces and as ambassadors and politicians, including as Governor General of India and as Prime Minister of the United Kingdom. The family is related to the British royal family through the maternal Cavendish-Bentinck line of Queen Elizabeth The Queen Mother. History The name Bentinck is a patronymic variation of the Old Germanic name Bento. The family is originally from the east of the Netherlands and is regarded as Uradel nobility, or noble from earliest times. The oldest known ancestor is Johan Bentinck, who owned land near Heerde and is mentioned in documents between 1343 and 1386. An important British branch was founded by Hans Willem Bentinck, 1st Earl of Portland, who accompanied William Henry, Prince of Orange to England during the Glorious Revolution. The head of this line was initially given the title of Earl of Portland (later Duke of Portland). In 1732, the title of Count Bentinck (Graf Bentinck), of the Holy Roman Empire, was created for Willem Bentinck, the second surviving son of the 1st Earl of Portland. A Royal Licence of 1886 was created which allowed the use of this title in Britain. The Royal Warrant of 27 April 1932 abolished the use of foreign titles in the United Kingdom but extended the special allowance in 13 cases, including the Bentinck comital title "during the lives of the present holders, their heirs, and their heir's heir, provided such heir's heir is now in existence." That exception has now expired. Another branch with the title of count existed in the Netherlands, but it died out in the male line. The Dutch and British branches of the family continue to exist and belong to the Dutch nobility, German nobility and British nobility. The Lordship of In- and Kniphausen The counts of Bentinck were sovereign rulers of the Lordship of In- and Kniphausen, a territory of two parts in and around what is now the city of Wilhelmshaven. Originally subject to Brussels, the general reorganisation of the Holy Empire in 1803 (Reichsdeputationshauptschluss) granted Imperial immediacy until the dissolution of the Holy Empire in 1806. The Lordship maintained a precarious independence until 1810, when France annexed it and the whole German North Sea coast to enforce the Continental System. At the Congress of Vienna in 1815, the Lordship was denied
