"Natural Born" comes from a contemporaneous reference for international law. It pertains to a person who is born of parents, both of whom are U.S. citizens. It does not primarily have anything to do with place of birth, but of parental nationality. The object is to remove any foreign allegiances or obligations from one's birth circumstances.
As a partial illustration of this point, my cousin was born of a mother (my aunt) who was a U.S. citizen and a father who was a French citizen, in France. She therefore inherited U.S. citizenship from her mother (no requirement to be born in the U.S.) and birthright French citizenship. She would not be able to run for president, but it does show that even partial citizen parentage endows citizenship.
