What I’m saying is that in the era of the revolution, that would never have happened.
Today, if you marry a princess of England, then your child will be a citizen at birth of the USA, provided you have met the residency requirements.
Maybe not. Is the princess subject to the jurisdiction of the United States? I would assume that she would enjoy diplomatic immunity and therefore would not. So under the 14th Amendment that may prevent automatic citizenship. An interesting legal dilemma.
