J Antonio Jarvis speaks of the Robles family a being the business representatives of the Rothschilds in St. Thomas but I am unclear if the Rothschilds involved are the same as the famous family of Mayer Amschel Rothschild.
I do know that the famous Rothschilds had operations in Havana and did business with August Shoenberg Belmont in New York who had been sent out by Alphonse Rothschild to work in Havana but remained on his own initiative in New York because it seemed more promising. My greatgrandfather did a few deals with the Belmonts financing New York subway lines.
