The meaning as understood by the Founding Fathers is the one that matters. That definition was found in The Law of Nations or the Principles of Natural Law (1758)
At least two meanings were “understood” by the Founding Fathers.
This one:
“United States Congress, âAn act to establish an uniform Rule of Naturalizationâ (March 26, 1790)”
And this one:
“United States Congress, âAn act to establish an uniform rule of Naturalization; and to repeal the act heretofore passed on that subjectâ (January 29, 1795)”
We don’t get to pick and choose which one we like as the 1795 one repealed (revoked, annuled) the 1790 one. The 1795 act has no reference to “natural born”.
