I also have a Facebook page for The National Society of Natural-Born Citizens of the United States. There is posting that will provide information of the source for the term "natural" and the definition as understood by the writers of the Constitution. Please visit us on Facebook.
The web site can be reached at natural-borncitizens.com; natural-borncitizens.org; or natural-borncitizens.net. Email will reach me at natural-borncitizens@peoplepc.com. Your questions will be answered.
Please purchase my recently published book, "A Guide to the Formation of the Constitution and the Source and Meaning of the Natural Born Citizen Clause with Plutarch's Lives of Solon, Themistocles, and Pericles and Ancient Roman Statutes and Citizenship Law." Not theory, and following the notes of James Madison, the intent behind the Deputies is open to you. This may be your first awareness of Roman Citizenship Law and the men Plutarch wrote about. It is a better education on the formation process than any student will be provided at College or University. You will be pointed in the intended direction the Deputies wanted the Nation to have as a future. The most important Article is Article V, the Amendment Article, to be used whenever the Law does not reflect the will of the People. The People control the Constitution. Without an Amendment changing Law, the Law does not change. Become educated and more aware of your responsibilities by purchasing and reading this book.
