in the words of Lord Coke in Calvin’s Case, 7 Coke, 6a, ‘strong enough to make a natural subject, for, if he hath issue here, that issue is a natural-born subject’; and his child, as said by Mr. Binney in his essay before quoted, ‘If born in the country, is as much a citizen as the natural-born child of a citizen…”

LOL!

If born in the country, is as much a citizen as the natural-born child of a citizen…”

There are 2 types of 'citizens' in that sentence.

Against my better judgment here is a more pertinent quote in language that ANYONE can understand:

Great empires and humble nations alike have made similar choices in determining who will be citizens. The world’s nations emphasize one or the other of only two methods for determining citizenship at birth. Most nations assign citizenship at birth according to the citizenship of at least one of the parents. A few nations, including the United States, assign citizenship on the circumstance of place of birth—within the territorial boundaries of the nation—regardless of the citizenship of the parents. While the United States also permits the children of its citizens born abroad to be considered U.S. citizens from birth, the predominant mode of birthright citizenship in this country, and the only one grounded in the Constitution, [FN1] is that which bestows citizenship upon anyone born on United States soil.

That is the very first paragraph.
