I am sorry if I misunderstood you. I had understood you to be saying that Yeates wrote that book. But, it does not matter who wrote the book. Whoever wrote that book and whoever wrote that footnote, it contained nothing more than a personal opinion that was supported by any primary sources of law. It is just an opinion. It is not a source of Constitutional law.
The book was the work of the entire Supreme Court of Pennsylvania. It was compiled by Samuel Roberts, but it was written with the Supreme Court Judges names prominently as authors of the work contained therein.
Again, the ENTIRE SUPREME COURT of PENNSYLVANIA.
I would say that gives it pretty solid judicial legs. Your response leaves me with the impression that you are dismissing it without actually giving it the consideration which it is due.
Certainly no equivalent law books have been presented which state that the U.S. unequivocally follows English Common law regarding citizens.
In any case, none has ever been presented to me.
This is how that book came to exist.
