I've tracked very reliably my family tree back to my great-great-grandparents plus once ancestor back one further. Of those 16 people, 12 were from the Naples, Italy area in Southern Italy (evenly split among Amalfi, Castellamare and Scafati). The other 4 were from Castelvecchia in the Marche region of Northeastern Italy. My DNA test showed: Central European 38%
Middle Eastern 46%
Persian/Turkish/ Caucasus 16%

I don't see how this is possible. How could nearly half be Middle Eastern?
If this data is right, the only explanation that I can think of is if the coast of the Naples area had a large dominant influx from the Middle East and Persia, but I've been doing research and can't find anything like that in Amalfi's history.
Is it possible that nearly everyone in the Naples area also shows that amount? Does it seem possible that none of those 16 people's parents bred with any Italians of Southern European descent?
