Hey, I had a look at it and transcribed the two marriage records for his two known sons. There are some clues in it and I wrote some notes, but since it is hard to read I was not able to identify any clear location. Maybe he lived near Marbach in Württemberg, but this would be like 70 km away.
I also attached copies of the records on his profile, so maybe someone else can have a look at it and identify the locations.
Next step might be to have a closer look at the godparents of all the children of his two sons and see if some of them came from a place like Marbach. Often godparents were close relatives.
