Searching for info on Samuel Gottlieb Hartmann born in late 1700's Wollin, Baltic Sea area. There are also connections to town of Grunow and town of Stolp. In the early 1800's, where these towns all in Pomerania? Are they now considered Brandenburg? Do these places still exist? I have found some records in Parish Berlin, Jerusalem Reierort, Brandenburg. Can anyone familiar with the area help me put this together.......Thanks in advance.
