I think it relates to north and south. Sunlight and warmth/cold. (If someone can explain that it is different between Germany and Scandinavia and Baltics, I'm listening.
Like there are other factors that override that default.)
Like does the amount of beer and wine and vodka make a difference.
Sometimes i think of how DNA sampling should become mandatory everywhere. It will clarify a lot, people will need to adjust their stories.
Baltic people are not germanic altough, and Dutch, Belgian and northern and central French are Germanic. Baltic people are close related to Slavic people, and have a very different language than Germanic languages. And Estonians are actually Finno-Uralic people just like Hungarians, Fins, Sami and Karelians (RUS). Europe is etnic very mixed but at the end we are all humans off course...
Pure Germanic languages that are still spoken are German (based on old high German), Dutch (based on old low German), Westflemish (very close to Dutch but different), Frissian, (based on old low German), Norwegian/Swedish/Danish/Icelandic/Faroese (all based on old Nordic). The Eastern branch of Germanic (the Gothic languages) dissappeared but still have some remains in modern Romanian, Italian, French and Catalan.
English and french are mix languages with a big part Germanic origin, more in Enlish then in French. English is Saxon & Anglish (low German) and Nordic mixed with latin and different Celtic (Brittonic, Scottisch, Pictian, Gaelic, Irish) languages. French is old Frankish (low German) and Burgundian (east Germanic) that is mixed with Celtic languages (Gallian, old Belgian) and Latin. And certainly today, all those languages influenced each other a lot.
