Michelle may well be the only smart one in the family.
It's only if Stanley Ann was married to the baby-daddy that place of birth becomes a problem.
Even if he was born in Africa to his single mother???
You may be correct on that, but I'm not sure if, in the case of child born out of wedlock whose father's identity is known and whose father is a British citizen, that such a child becomes a British citizen at birth - under the British law in effect in 1961.
Place of birth would still be a problem if Donofrio is right that NBC means being born on American soil as well as of citizen parent(s).
And the problem of loss of NBC through Indonesian adoption remains.
Not if he was born on foreign soil. Under the laws at the time of his birth, his 17 year old mother could not confer citizenship upon him if born on foreign soil. There was a residency requirement on U.S. soil that she failed to meet. If married to a foreign national, the problem is further compounded.
