Matadworf, I know "East Med" is a term long used on anthrofora, but it's meaningless, and therefore not used by academicians. If you mean Aegean or Anatolian Bronze Age, that would be closer to the reality.
Of all Greeks, Deep Maniots, Tsakonians, and Aegean Islanders are closest to their illustrious ancestors, the Bronze Age, Iron Age and Classical Era Greeks, because their isolation means they were less impacted by the Slavic migrations.
I've never seen Greeks plot as far north as the Marche. The furthest north I've seen them is southeast of Tuscany, and those were Thessalonians; the rest plotted east of Central Italian and further south, like Campania, Apulia, etc.
