3/ But this is not enough - I frequently translate tales from regions that are within modern-day Poland, Russia, and the Czech Republic, where the formerly German place names have changed into different languages. Sometimes Wikipedia can help me out, but often it does not. In such cases, I go to Arcanum Maps, which has historical survey maps as a map layer on top of modern-day maps. I can search for the nearest town I can identify, and then search the map for clues.
