their male-line descendants. Instead of Albert Edward, Prince of Wales (the future Edward VII of the United Kingdom) inheriting the duchy, it was diverted to his next brother, Prince Alfred, Duke of Edinburgh. Upon the latter's death without surviving sons, it went to the youngest grandson of Prince Albert and Queen Victoria, Prince Charles Edward, Duke of Albany. Charles Edward's uncle Prince Arthur, Duke of Connaught and his male line had renounced their claim. Although senior by birth, they were either not acceptable to the German Emperor as either a member of the British military or unwilling to move to Germany. The current head of the ducal branch is Andreas, the grandson of Charles Edward. Since the duchy was abolished in 1918, the heads use the title Prince rather than Duke.
