If Barbara is a matriarch of her clan, and this is a strong possibility, then keep an eye on women who visit her. One of them will kill the Grande Dame and take her position as matriarch. This is how power is transferred in an Illuminati bloodline. The Bush family is originally German, and the last surnames use by them in Germany were Volker and Scherff which suggest a connection with Thuringia, but possibly Black Forest too. Scherff is an interesting name because it means CHIP and in CUT OFF. There was a medieval German coin of that name that was CHIPPED OFF A SILVER ROD. I believe it to be roughly the equivalent of the English silver penny. The name is etymologically the same as the Russian RUBLE which was also chipped off a silver bar and comes from the Russian RUBITI which means SPLIT.
So, this suggests that their origin is as a branch, SPLIT off a major bloodline. If he is catholic, as some suggest because he seems to be connected to Jesuits and Knights of Columbus, then most likely is the Habsburg bloodline. But, caution, the bloodlines do hide their genealogy. If you look at the center of the red shield of the Rothschild coat of arms, it has a silver disc that could be a rough split from a silver rod. Does that mean they use SCHERF and SCHIFF for their branches. By the way SCHIFF is SHIP in English and comes from an old word meaning SPLIT and referred to boats that were not just dugouts but were built up from planks SPLIT from a log.
