Qualifications for the Office of President
Age and Citizenship requirements - US Constitution, Article II, Section 1
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; neither shall any person be eligible to that office who shall not have attained to the age of thirty-five years, and been fourteen years a resident within the United States.
This class of citizens is deceased and no longer eligible.
Thus the only class left is "natural born".
The definition at the time was "born in the country of parents(plural) who were also citizens". This definition was quoted in Supreme Court cases, including Minor.
Guess those Justices didn't know what they were talking about either.
