Cittadinanza per discendenza

Could your Tosi line qualify for Italian citizenship?

The largest share of Tosi arrivals came from Emilia-Romagna, most often from the provincia of Parma. 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.
