At common law, with the nomenclature of which the framers of the constitution were familiar, it was never doubted that all children born in a country, of parents who were its citizens, became themselves, upon their birth, citizens also. These were natives or natural-born citizens, as distinguished from aliens or foreigners. Some authorities go further, and include as citizens children born within the jurisdiction, without reference to the citizenship of their parents. As to this class there have been doubts, but never as to the first. For the purposes of this case, it is not necessary to solve these doubts. It is sufficient, for everything we have now to consider, that all children, born of citizen parents within the jurisdiction, are themselves citizens. Minor v. Happersett (1874) 21 Wall. 162, 166-168.
I would point out that Justice Waitie does not issue a definitive ruling on the natural born citizen definition, merely gives an opinion that some believe the matter is unresolved. Even if true, in any case the Ark decision came along 24 years later and put the matter to rest.
