Here ya go: a civics textbook from the 1970s.
Thorough discussion of Presidential eligibility; no mention whatsoever that the President must be born to two citizen parents. The only mention of parental citizenship is in the context of a child “born abroad of American parents.”
So I’ve now produced FOUR books, including two from the 1990s and one from the 1970s. Have you managed to locate even one that *supports* your recollections?
