I don't have time this AM to hunt it down, but posted on the Internet you can find an essay from 1916 by the pro-Woodrow Wilson Democrat Breckenridge Long - later FDR's anti-Semitic immigration commissioner - arguing that Charles Evans Hughes was constitutionally ineligible
Republicans scoffed at the argument against Hughes back then, and if the super-close race in California in 1916 had broken the other way - shifting 13 Electoral Votes from D to R - Hughes would have been accepted as US president, notwithstanding his British-born father.
It's been accepted precedent since 1881 that anyone born a US citizen can be president. It's irrelevant whether a parent was born abroad (Arthur, Hughes, Hoover, Obama) or whether the US citizen was born on foreign soil (George Romney 1968, John McCain 2008, Ted Cruz 2016).
