Jacob Bertschinger was born on Nov 20, 1828 in Aldingen (near Spaichingen) on the right side of the Neckar river in southern Germany). He came from a long line of farmers who had been living within about a ten kilometer radius of there for several centuries.
Genealogy.com is trying to tell me that he resettled to Calw in the Black Forest, a distance of almost 100 kilometers, which I view as highly suspicious and quite unlikely. I am bothered as much by the distance as by the cultural differences, and suspect that Genealogy has it wrong.
How could I verify whether Jacob really did move from Aldingen to Calw?
I will be going to Germany in early December and have a few hours to spare so I am also interested in how to find any information while I am "on location".
