Mountbatten-Windsor

Mountbatten-Windsor is the personal surname used by some of the male-line descendants of Queen Elizabeth II and Prince Philip, Duke of Edinburgh.

Under a declaration made at a Privy Council meeting in 1960, the name Mountbatten-Windsor applies to male-line descendants of Queen Elizabeth II without royal styles and titles.

[1] For example, Anne, Princess Royal, and Prince Andrew, Duke of York, children of Queen Elizabeth II, used the surname Mountbatten-Windsor in official marriage registry entries in 1973 and 1986 respectively.

[4] At the time of the 1960 declaration, palace officials claimed in private communications that it created a hidden surname that would emerge several generations later when some of Queen Elizabeth II's descendants were further removed from the throne.

[5] On the wedding of Prince Edward and Sophie Rhys-Jones in 1999, the Queen decided, with their agreement, that any of their future children should not be styled His or Her Royal Highness.
