Duke of Teck
In response to this, the Duke of Teck renounced, through a Royal Warrant from the King, dated 14 July 1917, his title of Duke of Teck in the Kingdom of Württemberg and the style "His Highness". Adolphus, along with his brother, Prince Alexander of Teck, adopted the name Cambridge, after their grandfather, Prince Adolphus, Duke of Cambridge.
