But two of them are William Rawle and James Kent. Men considered to be among the foremost legal and Constitutional scholars of their day and whose books and lectures were widely quoted in the courts.
I am familiar with a claim by Rawle, but I don't know of one from Kent. If you post it, and It supports your position, I will add it to my list of Historical references in support of the jus soli interpretation.
I am also familiar with this:
1922 US Assist Solicitor General, Richard W. Flournoy, citing ATTY General Black.
"Attorney-General Black, whose opinion of July 4, 1859, concerning the case of Christian Ernst, a naturalized American citizen of Hanoverian origin who was arrested upon his return to Hanover, has become a classic on this subject. It seems worth while to quote from this notable opinion:"
The natural right of every free person, who owes no debts and is not guilty of any crime, to leave the country of his birth in good faith and for an honest purpose, the privilege of throwing off his natural allegiance and substituting another allegiance in its placethe general right, in one word, of expatriationis incontestible. I know that the common law of England denies it; that the judicial decisions of that country are opposed to it; and that some of our own courts, misled by British authority, have expressed, though not very decisively, the same opinion. But all this is very far from settling the question. The municipal code of England is not one of the sources from which we derive our knowledge of international law. We take it from natural reason and justice, from writers of known wisdom, and from the practice of civilized nations. All these are opposed to the doctrine of perpetual allegiance. It is too injurious to the general interests of mankind to be tolerated; justice denies that men should either be confined to their native soil or driven away from it against their will.
