Durchlaucht
During World War I, King George V revoked recognition of the style "Serene Highness", hitherto used by some relatives of the British Royal Family who used German princely titles but lived in Britain. George V's queen consort was born ""Her Serene Highness" Princess Mary of Teck", and Prince Philip's mother had been born ""Her Serene Highness" Princess Alice of Battenberg". The Tecks (descended from the royal House of Württemberg) and the Battenbergs (descended from the Grand Dukes of Hesse and by Rhine) were compensated with multiple peerages, "viz." Marquess of Cambridge and Earl of Athlone for the former, and Marquess of Milford Haven and Marquess of Carisbrooke for the latter.
