"Ernest Augustus, Crown Prince of Hanover, 3rd Duke of Cumberland and Teviotdale (German: Ernst August; 21 September 1845 – 14 November 1923), was the eldest child and only son of George V of Hanover and his wife, Marie of Saxe-Altenburg. Ernst August was deprived of the thrones of Hanover upon its annexation by Prussia in 1866 and later the Duchy of Brunswick in 1884. Although he was the senior male-line great-grandson of George III, the Duke of Cumberland was deprived of his British peerages and honours for having sided with Germany in World War I. Ernst August was the last Hanoverian prince to hold a British royal title and the Order of the Garter. His descendants are in the line of succession to the British throne." - (en.wikipedia.org 21.03.2020)
