Thanks! There is no baptism record I can find for my relative in any of the records marked Augustwalde in this particular extract, he was born in 1858, and the book supposedly starts in 1872.
This is another strong contender, which is why I am confused when I go to try to find where exactly to look for records.
Augustwalde northwest of the city of Posen and midway between the two cities Arnswalde and Woldenberg on a map of the province of Posen from 1905 (areas marked in yellow indicate areas with a majority of Polish-speaking population at that time).
The village Augustwalde was founded in 1789 and until the second decade of the 19th century by the chief forester Schmidt.By buying adjacent areas, he expanded his possessions to a farm, which he sold in 1819 for 12,000 Reichstaler . In 1823 the geodetic Ferdinand Boeck bought up the property for 9,000 Reichstaler and extended it by acquiring additional plots of land.
Augustwalde had an important railway station on the railway line Stargard-Posen .
Until 1945, the village belonged to the district Arnswalde , from 1816 to 1939 to the administrative district Frankfurt of thePrussian province of Brandenburg , from 1939 to 1945 in the district of Pomerania -West Prussia in the province of Pomerania .With the communities Kranzin (Polish: Krzęcin ), Hitzdorf ( Objezierze ), Schwachenwalde ( Chłopowo ) and Sophienhof ( Przybysław ) formed Augustwalde the district Schwachenwalde in the district court area Arnswalde (Choszczno).
