At that point, the crown of Hanover went to William's younger brother, Ernest Augustus, Duke of Cumberland and Teviotdale under the Salic law requiring the next male heir to inherit, whereas the British throne was inherited by an elder brother's only daughter, Queen Victoria. Her offspring belong to the House of Saxe-Coburg and Gotha: in 1917 the name was changed to the House of Windsor.
