I'm hoping that someone can help me define a location during the mid-1600's through the mid-1700's. The town is named Gemen and I consistentlysee it referred to as Munster, Westphalen or Borken, North Rhine-Westphalen, in Germany. Checking history I see that much of Germany was considered Prussia and Westphalen was not in existence during this time period. The closest identity I can find is simply called the Duchy of Prussia.
Does anyone have any help for me?
