At birth, Prince William of Wales, the eldest son of Prince Charles, was given the names William Arthur Philip Louis.
His surname is either Windsor or Mountbatten-Windsor. His Grandmother, the Queen has stipulated that it is Mountbatten-Windsor, but the legal process necessary to change it to this from Windsor may not yet be completed.
Like his father, Prince Charles, and his paternal grandmother, Queen Elizabeth II, Prince William is of the Royal House of Windsor.
