The adoption of the Fourteenth Amendment obviously affects how we view natural-born citizens because for the first time there is a national rule of who may by birth be a citizen of the United States. Who may be born citizens of the States is conditional upon being born subject to the jurisdiction of the United States. The legislative definition of subject to the jurisdiction thereof was defined as Not owing allegiance to anybody else.
One universal point most all early publicists agreed on was natural-born citizen must mean one who is a citizen by no act of law. If a person owes their citizenship to some act of law (naturalization for example), they cannot be considered a natural-born citizen. This leads us to defining natural-born citizen under the laws of nature - laws the founders recognized and embraced.
I am an America natural born. I leave this country pregnant and have a child in Kenya or whereever. By my naturalization, my child is american born?
