THANK YOU!... and well said!
"No person except a natural-born citizen or a citizen of the United States at the time of the adoption of the Constitution shall be eligible to the office of President, [Footnote 7]" and that Congress shall have power "to establish a uniform rule of naturalization."
Thus, new citizens may be born or they may be created by naturalization.
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. 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. The words "all children" are certainly as comprehensive, when used in this connection, as "all persons," and if females are included in the last, they must be in the first. That they are included in the last is not denied. In fact, the whole argument of the plaintiffs proceeds upon that idea.

Under the power to adopt a uniform system of naturalization, Congress, as early as 1790, provided "that any alien, being a free white person," might be admitted as a citizen of the United States, and that the children of such persons so naturalized, dwelling within the United States, being under twenty-one years of age at the time of such naturalization, should also be considered citizens of the United States, and that the children of citizens of the United States that might be born beyond the sea, or out of the limits of the United States, should be considered as natural-born citizens. [Footnote 8] These provisions thus enacted have in substance been retained in all the naturalization laws adopted since. In 1855, however, the last provision was somewhat extended, and all persons theretofore born or thereafter to be born out of the limits of the jurisdiction of the United States, whose fathers were or should be at the time of their birth citizens of the United States were declared to be citizens also.
