Charles Edward was educated as a Prince of the United Kingdom for his first 15 years. He attended Eton College. As a grandson of Queen Victoria, the Duke was a first cousin of King George V and of the following European royals: Queen Maud of Norway, Grand Duke Ernest Louis of Hesse, Empress Alexandra of Russia, Queen Marie of Romania, Crown Princess Margaret of Sweden, Queen Victoria Eugenia of Spain, Emperor Wilhelm II of Germany, Queen Sophia of the Hellenes, Queen Wilhelmina of the Netherlands and Josias, Hereditary Prince of Waldeck and Pyrmont (the last two through his mother). Such was the interest Wilhelm II showed in his young cousin's upbringing that Charles Edward was known among the Imperial Court as "the Emperor's seventh son". His mother drummed into him endlessly the importance of "becoming a good man, so you bring no shame on Papa's name".
