“Barry was a born British subject. Inherited, by birthright, from his foreign father.”
Ironically, I have a dual citizenship brother-in-law who was born in US but has a non-custodial British dad. In any case, I was unaware that you could shed your dual citizenship if your dad dies or abandons you???
The framers had a reason for putting it in there...agreeing to the requirement without debate. Further, there doesn't appear to be any debate on that particular issue during the ratification process in any of the several states at the time. They all knew what it meant, and all agreed it was important to the point of not debating it's merit or need.
