Your very first link makes no reference at all to marriage, patlin. Perhaps you’d care to point out why you feel these to be pertinent.
Commentaries on American law, Volume 2 By James Kent
pg 70...Kent speaking of inheritance per US laws of inheritance/citizenship by descent: “...and if he dies within the six years, his heirs being inhabitants of the United States, take by descent, equally as if he had been a citizen.”
Supreme Court Justice Joseph Story, founder of Harvard law school cites in his treatise on conflicts of laws 1834:
§ 46. Without speculating upon all the various cases, which may be started upon this subject, it may be useful to collect together some of the more important rules, which have been generally adopted, as guides in cases of most familiar occurrence. First, the place of birth of a person is considered as his domicil, if it is at the time of his birth the domicil of his parents. Patris originem unusquisque sequitur.1 This is usually denominated the domicil of nativity, domicilium originis. But, if the parents are then on a visit, or on a journey (in itinere), the home of the parents (at least if it is in the same country) will be deemed the domicil of nativity.* If he is an illegitimate child, he follows the domicil of his mother. Ejus, qui justum patrem non habet, prima origo a matre.* Secondly, the domicil of birth of minors continues, until they have obtained a new domicil. Thirdly, minors are generally deemed incapable, proprio marte, of changing their domicil during their minority; and therefore retain the domicil of their parents; and if the parents change their domicil, that of the infant children follows it; and if the father dies, his last domicil is that of the infant children.4 Placet etiam filiumfamilias domicilium habere posse, non utique ibi, ubi pater habuit, sed ubicunque ipse constituit.

You have a child born to parents from 2 different countries. They each hold citizenship in different countries. For the citizenship of the child born either in wedlock or out of wedlock, you have to go to International Private Law aka International Private Laws of Nations and you have to look also at the treaties between the countries at the time of the child's birth. At the time of Obama’s birth, England did not recognize SAD’s citizenship if the marriage was legit, thus Obama was born a Brit & nothing else. If the marriage records are fake & he was born a bastard, he is was born soley an American citizen aka a NBC. GET IT!!!!
