I found a collection of old photographs of the town of Schönlanke in Netzekreis, Prussia. This was the closest town to where many of my Schmidt and Winkelmann relatives lived in the 1880s and 1890s.
The Lutheran (Evangelical) church is prominent in several of them.
Carl Friedrich Schmidt married Wilhelmine Winkelmann in Schönlanke, so that church may very well be where they were married in 1859.
There are many photos of city life and city sites. The photos seem to range from around 1890 to about 1940. Several of them show, for example, “Adolf Hitler Street”, which I assume did not exist prior to about 1936. There are also some photos of the beautiful lakes and countryside around the town itself.
