Every genealogist wants to find the place of birth for their immigrant ancestors. I know I was doing a happy dance when I found where my maternal great grandfather was born. Johann August Fredrich was born 14 January 1845 in Gorsin, Bromberg, Posen, Prussia. I found this information in a baptismal record. The information from the church record allowed me to look for more information on Gorsin.
The first place I looked for information was meyersgaz.org The entry for Gorsin can be found here. You can see a historical map at Meyers Gaz, too. The red placemarker is where Gorsin is. I zoomed out on the Meyers Gazetteer map in order to see where Nakel was. Nakel is on the left side of the map. The church in Nakel is where Johann August was baptized.
Another tab on Meyers Gazetteer is Ecclesiastical. Information about area churches is included on this page. The Protestant church in Nakel is 5 miles from Gorsin.
Today Gorsin is Gorzen, Poland and Nakel is Naklo nad Notecia, Poland.
