The term “natural born citizen” was used by John Adams in proposed drafts of the Treaty of Paris circa 1783.
Perhaps you could provide a link to these elusive "drafts of the Treaty of Paris circa 1783."
What remains is that the free, sovereign and independent pre-Constitution State of Maryland in a statute stated, "the marquis de la Fayette, and his heirs male for ever, shall be, and they and each of them are hereby deemed, adjudged, and taken to be, natural born citizens of this state, and shall henceforth be entitled to all the immunities, rights and privileges, of natural born citizens thereof...."
I provided link, cite, and quote of a statute giving natural born citizenship to Layfayette who had zero American parents.
It was an honorary naturalization.
Naturalization under the current Constitution falls under Article II (powers of Congress).
NFN but the 14th Amendment is really nothing more than a glorified naturalization statute.
The language you refer to with respect to Lafayette is similar in a certain way to that used by Adams in his treaty draft. Rights held by U.S. NBCs granted by (draft) treaty to British natural born subjects.
Busy now. Go look for it, you’ll find it.
Use the search term “plenipotentiary”.
