Mountbatten-Windsor
Mountbatten-Windsor is the personal surname of some of the descendants of Elizabeth II and Prince Philip, Duke of Edinburgh under an ambiguously-worded Order in Council issued in 1960, and as such a cadet branch of the House of Schleswig-Holstein-Sonderburg-Glücksburg (known as the House of Glücksburg for short), which in turn is a branch of the House of Oldenburg.
