[[ Thomas Jefferson wrote Virginias birthright law of 1777 requiring the father to be a citizen.
We can say with confidence that a natural-born citizen of the United States means those persons born whose father the United States already has an established jurisdiction over, i.e., born to fathers who are themselves citizens of the United States.

The natural born Clauses origins have been traced to a July 25, 1787 letter from John Jay to the presiding officer of the Constitutional Convention, George Washington. Jay wrote, Permit me to hint, whether it would be wise and seasonable to provide a strong check to the admission of Foreigners into the administration of our national Government; and to declare expressly that the Commander in Chief of the American army shall not be given to nor devolve on, any but a natural born Citizen. ************************************************** The natives, or natural-born citizens, are those born in the country, of parents who are citizens. As the society can not exist and perpetuate itself otherwise than by the children of the citizens, those children naturally follow the condition of their fathers, and succeed to all their rights. The society is supposed to desire this, in consequence of what it owes to its own preservation; and it is presumed, as a matter of course, that each citizen, on entering into society, reserves to his children the right of becoming members of it. THE COUNTRY OF THE FATHERS IS THEREFORE THAT OF THE CHILDREN. Vattel, Citizens and Nations, par. 212
Having jurisdiction over, is not precisely synonymous with being present in a jurisdiction. Mexican nationals birthing children here, are granted citizenship by Mexico (as I understand it to be) regardless of how we in the U.S. simultaneously practice a sort of "good enough" mentality concerning U.S. citizenship for those born here, which sort of thing gives rise to possible split alliegences.
La Raza (The Race), anyone..?
