The word natural comes from Kind and Gecynde. Kind and natural have the same meaning.
When the Founders used the term natural born citizen they placed this type of citizen into a Kind.
Kind comes from the old Anglo Saxon word gecynde.
It is my contention natural born Citizens are the descendants created after the ratification.
It has to be determined if the 14th Amendment can alter the Kind or natural born citizen.
Here is a list of books in my google library explaining Kind and Natural

You mean "if" it altered. Of course it can. An Amendment can alter any previous constitutional entry.
