Under Vattels Law of Nations ( which our Founding Fathers used in defining Natural-Born Citizen). The Country of the Fathers is therefor that of the Children; and these become true citizens by their Tacit consent.
So Vattel's book was referenced in the Constitution? Was it made clear to all the signers and those ratifying the constitution that natural born citizens (which happens to be in lower case in the Constitution) was referring to Vattel's definition rather than the more obvious definition of someone who became a citizen at the time of their birth?
I say,that, in order to be of the country, it is necessary that a person be born of a father who is a Citizen; for, if he is born there of a foreigner, it will only be the place of his birth and Not his Country!
So what would be the citizenship of someone who's father is unknown? Would the be in perpetual limbo? An illegal alien wherever they might go?
If Obama was born outside of this nation according to our laws at the time, he would not have been a citizen at birth, and therefore wouldn't be a natural born citizen. However, it does not seem clear to me that those signing or ratifying our Constitution had all read Vattel or understood that term to be as he defined it.

Yes, they were all familiar with natural law, since they were founding a republic based on natural law. They would have all been well aware that the draft requiring the President merely be "born a citizen" had been rejected in favor of a stricter requirement that the President be a natural born citizen because that would provide a stronger check on foreign influence in the executive. They were aware that the condition of the father naturally passes on from the father to the child. They were not being bamboozled by Gen. Washington and John Jay. They knew what they were doing. They were not as ignorant and illiterate as you seem to be.

The condition of a bastard follows the condition of the mother. This is very basic stuff. Try reading a book some time.
Hope this helps.
