Oh yes; I thought it was obvious but then I re-read what I wrote and it was not obvious. My point was to show how it's rather normal to have languages mixed up geographically in such a way that can explain why the same language family ends up in central italy and in an island in greece, by observing that it happens also with languages for which we have much more available data.
