Sorry gato, you are not exactly on target with your analysis.
I said, if they were married, and you give me the rules for out of wedlock births. I looked all this stuff up nearly a year ago, and while I may have to find the citations again, I remember what I found. Not that I trust to the memory, I look it up again.
IIRC, I was responding to the assertion that if the mother is a citizen, then so is the baby, regardless of where born. That was an absolute statement, and I showed that in some casese, it's just not true. Doesn't have much to do with "natural born" however, per the State department link I provided in two posts above, plus a simple reading of the Constitution's delegation of powers to Congress.
