Plus one more detail:
West Pomerania, where is Bobolice, became part of Brandenburgia (German Principality) in 1648. There is also a history of Jewish community in Bobolice. After the first partition in Poland Prussian king (Fryderyk II) removed 7000 Jews from the region to Poland. The number of Jewish families in Bobolice dropped from around 25 to 6.
Also, another interesting fact from the document below, in 1812 Germans became something what could be called 'Jewish germanisation'. Meaning, they would get the same citizen rights as German citizen IF they change their surnames and names to German, start speaking German and change the clothing/way they dressed to 'European' and had to convert to a christian faith in some cases.
The mass migration, mainly to Germany and both AMericas, from Bobolice and area peaked mid 19th century
