on vanderbildts and the french dynasties:
many are relevant, and there is something to the assertion in Springmeier's book that the 13th bloodline is merovingian. Franks/Frankism/sabbateanism. Look into people like Ben Frank-line and his hellfire club, bizarre writings on sexuality. the thread goes back much further than america. some quick bullet points:
-Capetians (big head dynasty). many such physical deformities are present in the history of france and are prominent in the mythos surrounding melusine for example. the DNA is relevant (Cro-Magnon). other famous deformities that play a role in french history are webbed hands and feet. templars/cathars/huegenots related more than just a simple genetic variation https://en.wikipedia.org/wiki/Cagot
-Ramnulfids
this is where we get virginia elite Randolph clan. thomas jefferson was matrilineal Randolph, also involved in neuf soeurs frank-masonry or Grand Orient lodge. french diplomat like b. franklin. quite a taste for french wine. died in debt just like is father to french bankers, despite being president, ambassador, architect and arguably one of the greatest minds of the time. other randolphs of note include P.B. Randolph, early sex magician and hemp importer.
-templar bloodlines out of Belgium/France dominate the genealogy of US presidents. notably Ian Flemming is also belgian templar descent, instrumental in forming MI6/CIA, heir to flemming bank fortune, possibly poisoned/killed for revealing too much in his books about swiss templars (spectre).
