A lot of people went from Albania to Italy in the Middle Ages.
It was typical to find Balkan people in the ranks of the condotierri. https://en.wikipedia.org/wiki/Stratioti

Some Albanians and some Croats fled to Italy to escape the Turks in the Early Modern period (and their descendants continue to speak their ancestral languages) but I think they are confined to fairly small parts of Italy. In ancient times one of the Indo-European languages spoken in southeastern Italy was related to an Indo-European language spoken on the eastern side of the Adriatic.

Armenian is an Indo-European language, the only one in its group, but its closest relative is supposed to be Greek. It's also related to the Indo-Iranian branch of Indo-European, and of course more distantly to the other branches. It absorbed loan words from many other languages over time including some from the indigenous non-Indo-European languages of the Caucasus region.
