I believe that the royal families of Europe have been merging their bloodlines for some time. So even though Soros is a Habsburg/Catholic and Windor or Saxe-Coburg-Gottha is Protestant, they are now allied and interbreeding as well. It may be that they have now become one royal bloodline, and therefore they, the Rothschild's and the House of Saud are the only 3 branches left of the Illuminati.
