So then he was an American citizen......or am I missing something here?
You must read the entire article.
If you are born in the U.S., are you not a natural citizen?
Yes, you are missing something.
Allen’s birthplace made him an American AT birth, but he was not a citizen BY birth because his father was a British subject.
IOW, Allen was an American citizen, but he was not a natural born citizen and, therefore, was ineligible to be president.
Unlike Berg’s suit which is based on the citizenship law prevailing in 1961 and the possibility, supported by reports of Obama’s Kenyan grandmother’s recollection, that Obama might have been born in Kenya, Donofrio’s suit is based on the legal theory that ‘natural born citizen’, as the founders meant it, excludes anyone who was a dual citizen at birth, or thereafter. If his theory were accepted by the courts, anyone whose parentage or location of birth created dual citizenship would be barred from the Presidency.
Because woman had no standing in the 1800’s only men could bring the linage forward!
