Aren’t Queen Eliz and Charles, German?
Wikipedia: The House of Windsor is the current Royal House of the Commonwealth realms. It is a branch[dubious – discuss] of the German House of Saxe-Coburg and Gotha (German: Sachsen-Coburg und Gotha), which adopted the English name Windsor by a royal proclamation on the 17 July 1917. The most prominent member of the House of Windsor is Elizabeth II, the reigning monarch over the Commonwealth realms.[1] However, the head of the House of Windsor (cadet branch of Saxe-Coburg-Gotha) is Prince Richard, Duke of Gloucester, as the senior male-line descendant of King George V, who founded the house by changing its name from Saxe-Coburg-Gotha to Windsor. The overall head of the House of Saxe-Coburg and Gotha, including the Windsor branch, is Andreas, Prince of Saxe-Coburg and Gotha. The heir to the thrones of the Commonwealth realms, Charles, Prince of Wales, is a member of a distinct House of Windsor, a cadet branch of the House of Schleswig-Holstein-Sonderburg-Glücksburg as membership to European royal houses is determined by patrilineal descent.[citation needed]
