The Duke of Edinburgh and consort of Queen Elizabeth II, born June 10, 1921, is originally a prince of the House of Schleswig-Holstein-Sonderburg-Glücksburg, whose members include the royal houses of Denmark and Norway, the deposed royal house of Greece. His father was Prince Andrew of Greece and Denmark, whose ancestry was Greek and Russian. Philip served in the Royal Navy during World War II. He received the title of His Royal Highness from George VI the day before he married Elizabeth on Nov. 20, 1947. Because of Philip’s surname, the male children of the couple use the surname Mountbatten-Windsor.
