Here I'll make it easy for you. I'll underline the answer for your convenience:
"The Constitution does not in words say who shall be natural-born citizens. Resort must be had elsewhere to ascertain that. 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." [Minor v. Happersett , 88 U.S. 162 (1875)]
“Some authorities go further and include as citizens children born within the jurisdiction without reference to the citizenship of their parents.” [Minor v. Happersett , 88 U.S. 162 (1875)]”
WKA went further...
Also note: “These were natives or natural-born citizens, as distinguished from aliens or foreigners.”
Hmmm...only two classes in that decision: “natives or natural-born citizens” and “aliens or foreigners” whose citizenship rested on naturalization.
