Before the Constitution the closest reference we have to Natural Born Citizen is from the legal treatise “the Law of Nations,” written by Emerich de Vattel in 1758. In book one chapter 19,
§ 212. Of the citizens and natives.
“The citizens are the members of the civil society; bound to this society by certain duties, and subject to its authority, they equally participate in its advantages. The natives, or *****natural-born citizens*****, are those born in the country, of parents who are citizens.
True, but common sense tells us the same. Being born on the soil cannot be of more importance than the nationality of the parent(s), especially if the parents are transient, as is the instant case, i.e., Dear Leader.
