Just thought I'd chime in here although I admit that I am out of my depth in these matters. When you mentioned Churchill and Shaw, I thought of Sir William Stephenson, the financier, friend of Churchill and man in charge of UK skulduggery in the US during WW2.
If the following linked material is accurate, there is an overt connection between Stephenson and Shaw, which may have been preceded by a covert wartime connection. That brings you to one degree of separation between Shaw and Churchill.
Here's the link.

The (Stephenson founded) World Commerce Corporation also played a useful part in the development and rehabilitation of economically backward countries. As one American newspaper editorial put it at the time, "if there were several World Commerce Corporations, there would be no need for a Marshall Plan". Barter trade was facilitated on a massive scale. A typical transaction took place in the Balkans in 1951. Yugoslavia and Bulgaria were short of dollars and also short of medicinal drugs. But each country had about $300,000 worth of paprika on its farms. World Commerce accordingly exchanged a year's supply of penicillin and sulfa for the paprika, which they then sold on other markets. While normally working on a commission basis, the Corporation would sometimes forgo its profit if it felt it could help an impoverished or economically backward country by giving it the facilities of its international connections."
The North Jamaican Hillowton property was later transformed to Tryall, the exclusive club of John Connally, Paul Raigorodsky and many others of the cabal. World Commerce Corporation received funds from the U.S. International Cooperation Agency and worked closely with Clay Shaw's World Trade Development Commission and Permindex's various World Trade Centers.



Most helpful, thanks.
