10/ I've found out two Sarbinowo in Poland, one near the Odra & Warta confluence, the other on the Baltic sea near Koszalin ; a Sarbia again on the Baltic sea. Are these names connected with the Serbs/Sorbs ? 20/ Does Serbske Kamenice (in the Czech Rep.) (it seems that this city has been renamed since, but I'm not sure) take is "Serbske" prefix out of being in Czech part of Sorbian Lusace or in the ancient White-Serbia ? Does anyone know which present towns are on the territory of this former White-Serbia? Thanks a lot.
