Yes. I make no claim to be a great historian, but this is no surprise to most anyone with any interest. Or so I would have thought.
Two other interesting factoids are that high definition scanning and imaging revealed that Jefferson initially wrote the word “subjects” in an early draft of the Declaration of Independence then scratched out and obliterated that word and morphed it, writing the word “citizens” right on top of where it was, and that Washington’s administration checked out a copy of Vattel’s Law of Nations from the New York Public Library, which never got it back until Mount Vernon gifted an original replacement copy to it about ten years ago or so.
