@yetos, thank you for your response!
From what I known, these Karpathians far predate the 20th century population exchange, thus this look does not derive from hellenized anatolians nor gypsys,
Also the extent of them being early neolithic, pre-Greek is most likely insignificant.
can you please elaborate on where do you think they came from?
if we exclude and we are certain that not pre-Greek population,
then the only possible is to be Hellenised population from Antique,
Christians from the areas that Islam expand, like Syrria or Turkey/Armenia/ Iraq or more far East or South.
there were migrations from Egypt Jordania and Syrria at 6-8th century,
For example mt Athos is the replacement of the Egyptian desert monks
the first monks were at Egypt, then Kappadokia, and then moved to Athos
if they are connected with Rhodos island,
they can also be populations that came with return of Crusaders,
or Knights, as υποστατικοι. (protected Servicing-support communities)
but better serch if they are ancient population,
especially their autosomals, they may even say how long time are in the area
they also have a look of S Caucasian areas.
do they use an endonym for their villages, or have they any special vocabulary?
They have an Anatolian phenotype also,
my mind is going either to pre-Mycenean era,
either the Byzantine era, from 7th century Ad till Matzikert 12th century,
there were moves of populations that era due to expand of Islam and Turks.
I mean they could also be from Killikia and moved West then times of Seljuks
,
but primary is an autosomal search so to exclude possible Neolithic population.
