There are many Italians who went to South America, some because in the late 1800s, early 1900s the United States denied entry to Italians (particularly southern Italians who sought entry into the U.S.) Many Italians or their families ended up in Argentine, e.g., the Pope's family. I have cousins that are in Buenos Aires, which gives that city a very Italian flavor. Fernando is not an Italian name, however that is probably not his real name and even if it were there is nothing to say that he could not be Italian.
