BTW, that article cannot in any way be cited as law or even judicial dicta. Jacob Howard’s explanation of the clause as he helped draft it is more compelling in that regard. What this article does though is to point out the common contemporary understanding of those who ratified it which, from the perspective of an originalist, is just as important as the intent of those who drafted the legislation.
See Here.
So it was the predecessor of 8 USC 1401? Be interesting to know the legislative history.
Would think it would have been referenced in all the famous cases - Ark, Elk, Slaughterhouse.
