There is some fascinating history behind that pamphlet in James Madison’s possession, it wasn’t just some stray compilation of complaints with obscure origins. Madison knew the author as did George Washington.
All in attendance at the Convention knew who he was, he was regarded as one of the preeminent legal minds of the time. The author was also the author of the Virginia Declaration Of Rights and a Founder himself, who walked out on the Convention in Philadelphia precisely because it contained no Bill Of Rights, along with Elbridge Gerry.
He’s known in some circles as The Forgotten Founder. But he’s not forgotten in Virginia and he’s not forgotten here.
His name was George Mason.

The State ratifying conventions submitted over 110 amendments. I have run across Virginians who think VA alone submitted or had Bill of Rights.
Current events of 1788 and subsequent history proved Madison’s view; parchment barriers are ineffective unless backed up by opposing interests.
