Somewhere I have a book that list some of the other German Royals that served in Germany's military during the war. Rupprecht however, would probably make a pretty good alternative to the House of Hollenzollern. His family had connectitions to the the British Royal Family dating back to the English Civil War. He was also quite popular with veterans of the First World War. He was strongly antiCommunist leading to the crushing of Reds in Bavaria and he was also anti-Nazi,
