Washington, Adams, Jefferson, Madison, etc. were all born to parents who were obviously British subjects, not U.S. citizens.
Unless there is some sort of "grandfathering clause" in the Constitution, then being born in one of the 13 Colonies was good enough for them to be POTUS-eligible.
Guess what! There is a “grandfathering clause.”
The addition of a grandfather clause in this paragraph says a lot as to the meaning of natural born. The first thing it says is that being born in the US is not enough to be natural born, otherwise the grandfather clause would not be necessary. The writers and delegates, having been born in the US, wanted to be eligible for the presidency, but most were the children of British subjects. Knowing that that eliminated them from being natural born and, thus, from eligibility, they included the grandfather clause which expired when the last person alive at the time of the ratification of the Constitution died. So, being a native born citizen is not the same as being natural born. If it were the framers would not have included the clause.

The comments on the page are interesting as well.
No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President[....]
The part saying “or a Citizen of the United States, at the time of the Adoption of this Constitution” IS the grandfathering phrase. How did you miss it?
