"Natural born" had a meaning in 1787. Place of birth, plus citizenship of parents, were factors in this determination.It is why the phrase even appears in the eligibility requirements for President.

I respectfully disagree, in part.
It's the parental citizenship that matters. The place of birth is immaterial.
The phrase 'natural-born comes from Natural Law...a.k.a. the Law of Nature and Nations by Vattel. In a nutshell, natural born citizenship is hereditary...you get it from your parents. If they are either a natural-born or naturalized citizen at the time of the birth of the child, the child is natural born - and it doesn't matter where the birth occurs.
I do how ever, agree the 14th does not convey natural-born citizenship.
By it's current interpretation, it splits the Original meaning of natural born into a separate type of citizenship: native born, or a naturalization-at-birth on children of aliens and foreigners.
And it is blatantly unconstitutional.
