Nearly every pope has been born and raised in Italy, with about half a dozen exceptions. But the one guy who is NOT from Italy is “the Roman” because he has parents who are from Italy? Please, it would make more sense if he were called “Peter the Not Roman.”
St. Francis of Assissi’s was born Giovanni di Bernadone. His FATHER was Pietro. Hence, Giovanni di Pietro di Berndadone. (Francesco was only a nickname, not a birthname.) So you’re basically saying that Jorge is Petrus because Jorge named himself Francis after someone who’s father was Pietro, which is Italian for Petrus. That’s two or three degrees of separation.
