One of the conditions of citizenship is renouncing previous citizenship, so I was wrong in my previous answer.
Italy would have no claim on you.

Born here of citizen parents is the standard.

I never renounced Italian citizenship. Nor did my mother or my grandfather, since they never knew they had it. The only one who renounced it was my great-grandfather, and that was after my grandfather was born. As I said, under Italian law, I already am a citizen.

Interestingly, Ronald Reagan was only one generation removed from being able to get an Irish passport. Under their law, citizenship can pass down as far as a grandchild, and Reagan was the great-grandchild of an Irish immigrant who become a citizen only after Reagan's grandfather was born.

Have to disagree, there are only two types of citizens, natural born and naturalized. I see nothing in the constitution or any US law defining any other type of citizen.
