Prince Ernest Augustus, 3rd Duke of Cumberland and Teviotdale
Ernst August, Crown Prince of Hanover, was the only son of George V of Hanover and Marie of Saxe-Altenburg.
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.
His descendants are in the line of succession to the British throne.
His successor Ernst Augustus, Duke of Brunswick and Prince of Hanover, Prince of Great Britain and Ireland, was the youngest child of Crown Prince Ernest Augustus and Princess Thyra.
 When Ernest's older brother Prince George died, the German Emperor sent a message of condolence to the Duke.
In response the Duke sent his only surviving son, Ernst, to thank the Emperor.
In Berlin, Ernst met Emperor William II's only daughter, Princess Victoria Louise of Prussia.
