When I was a kid I seem to remember the requirement that a person had to be born 2nd or 3rd (not sure) to be President. Does anyone remember that?

You had to be named Trey.
John Adams was a first-born child. So were several later Presidents including Polk, Truman, LBJ, Ford, Carter, Clinton, and George W. Bush.
