No, I haven't.
It's true that if George Washington and Thomas Jefferson hadn't been natural born citizens, then the grandfather clause would have made them eligible.
But they never needed it. They were natural born citizens.
Story states that it was passed "out of respect to those distinguished revolutionary patriots, who were born in a foreign land, and yet had entitled themselves to high honours in their adopted country."
That means it specifically WAS NOT PASSED for the sake of George Washington, et al. Again: They didn't need it. They were natural born citizens.
Incidentally, if the birther claim that "you couldn't be a natural born citizen, because the United States didn't exist when the Founders were born" were true, then George Washington could not have been inaugurated as President. Because his first inauguration came less than 14 years after the Declaration of Independence.
Justice Joseph Story was born in 1779. Do you think he contributed much to the Constitutional deliberations being that HE WAS ONLY eight (8) Freaking years old?
He is, like MOST of the people you cite, not a member of the group who deliberated it, and in fact came along AFTER THE FACT. As is common with the people you always cite, his opinion is "hear say" and speculation, not first hand knowledge.
