Cingull might be Latin, as there seems to be a lot of Latin words in Albanian.
My family's mostly Greek and from Lakonia (near Sparta), but my great grandfather (the Albanian one) came from Kranidi (Northern Peloponisus).Also, I know that he had a lot of relatives in Spetses, so he might be originally from there.The Spetsiotes, as you might know, are almost entirely of Albanian stock, which is what led to suspect that I might have some Albanian ancestry.
My parents never told me that there might be some Albanian in the family; like the Greeks you described, my mom is quick to make excuses for relatives who speak Arvanite.
I think Greeks do this because modern Albanians are Muslim.I don't see a problem, however, as Greeks and Albanians, to me, seem derived from the same Balkan tribes.There was no clear-cut difference in ancient times: the southerners were just more civilized, while the Dinaric hillbillies were more isolated and, hence, more "backward."Pretty fascinating stuff, all the same.
