It is a given that the undefined terms in the Constitution are defined in the English Common Law
"The first and most obvious division of the people is into aliens and natural-born subjects. Natural-born subjects are such as are born within the dominions of the crown of England, ... and aliens, such as are born out of it. "
- Blackstone, Commentaries on the Laws of England
So apparently English Common Law doesn't differentiate between category 2 and 3 either.
Blackstone also says this:
"The children of aliens, born here in England, are, generally speaking, natural-born subjects, and entitled to all the privileges of such. In which the constitution of France differs from ours; for there, by their jus albinatus, if a child be born of foreign parents, it is an alien."
” a child be born of foreign parents, it is an alien”
Anchor babies aside, that defintion fits precisely with our law saying a person (such as John McCain) born in another country to US citizen parents, is a NBC of the USA. It can not be both ways, one born is either a citizen of the country born in or not decible by parentage.
