I had the results of my "true ancestry" back. You upload DNA data and they compare it to DNA obtained from ancient burial sites.
Interestingly, I had a strong match to "Hellenic-Roman", but nothing turned up for "ancient Greek". Older matches were Anatolian and Canaanite regions and Minoans.
Were the "Hellenic-Romans" not originally from ancient Greece?
Did "Hellenic Romans" not all have "ancient Greek" ancestry?
