I understand that the eastern region of Belgium including Malmedy and St. Vith were a part of Prussia during the 1800s until 1918. I am looking for a detailed map of this area, in particular for the town of Langenfeld nearby Malmedy. (I was sent a general map showing Malmedy in Prussia for this period, but it had few details)
If anyone can help locate such a map, or at least verify Langenfeld's existence in the 1800s and provide a little more info on its precise location and any other points of interest, I would be very grateful.
