Could your De Nizza line qualify for Italian citizenship?
The largest share of De Nizza arrivals came from Molise, most often from the provincia of Isernia. If one of them is your ancestor, Italy may recognize you as a citizen under jure sanguinis (citizenship by descent).
The surname alone does not decide it. Each generation between that ancestor and you does: who naturalized, and when. Since the 2025 law, the number of generations matters too.
The checker goes back through your line one generation at a time. It is not legal advice, and it does not search for records.
