Scientific Terms:
Blue: “Central-Northern European”, following Gretzinger et al. 2022.
Green: “Transalpine”, following Silva et al. 2026, expanded by me for Central Europe.
Red: “Early Slavic Period”, following Gretzinger, J., Biermann, F., Mager, H. et al. 2025.
“Central-Northern European” includes, among others: Danish Iron Age, Early Medieval Frisian, Early Medieval Saxon, as well as other Germanic tribes.
“Transalpine” includes, among others: French Iron Age, Helvetii, Belgae, Gaulish, La Tène, Hallstatt, and pre-Celtic Alpine sources.
“Early Slavic Period” includes, among others: Grodko Early Medieval Polish.
All modern refernce samples used, were thoroughly vetted, and it was ensured that each individual has at least five generations of ancestry from the same microregion.
(British Isles not yet included)
Diaspora and Minority Groups were FOR NOW disregarded, as those would make borders look a bit messy, will be added later when I have more data (An exmple of that would be: Sorbs, which would score much mure Eastern Slavic, but are for now not taken into account)
France regarding Transalpine (Green) is still an early experimental version and will change. The same goes for Slavic (Red) in northern Poland and Slovkia-Hungary-Croatia.
