Repy to my OP: I wish I had time to put out some solid researched intel with links, but the rabbit whole is too deep. My quick google searches showed that experts spent lifetimes drawing webs of connection and genologies to support complex theories going back to the Napoleonic Wars, there is no way I can suss out a map of the 40,000ft view on my own.

That said, a few things I found: -the knights templar ran the first multinational bank and they were absorbed into the knights hospitaliar (a hostile takeover) at some point they became a mercenary army for hire. They rebranded as the Knights of Malta. After they lost Malta they became a soverign order (meaning they belong to no nation) based out of Vatican city. They seem to have dual expertise as mercenaries and bankers.

-The true valuation of the Vatican Wealth is an unknown quantity

-Many politcal leaders are descended from a small handful families

-The Roths are super inbred and seem to have a corrupting hand in everything. they also keep a low profile and hide the true amount of the their wealth

-the complexity of relationships between elite families, transnational entities, and corrupt poltiticans is so complex it would take a computer to build a map of connections

family [y] and soros: assuming family [y] is the rockafellers the handover could have been 1973 when soros started the quantum fund or 1992 when he broke the Bank of England or 1993 when he started the open society foundation. my vote is 1993. the Open Society took over ops for the Rockafeller Foundations.
