The history for this side of the family is short, they did not arrive in America until mid 1800's and before that there not many records available due to the changes of governments and the general lack of a centralized depository of data.
Polish, Germans, Russians, Austrians, Prussians or Pomeranians? Who
declared to the immigration authorities that they were born in Poland? After all, the fact was that Poland did not exist, and the American immigration officials were at lost as how to classify the new arrivals.
At the
time of the Shombergs, Dombrowski, Dishers emigration (1820-1880), their land
was part of the Prussian Empire. The Polish–Lithuanian Empire ended about 1772
with the take over from Prussia. Not until 1919 did it become part of Germany
or Poland. How they really defined themselves we will never know for sure but the
descendants eventually settled in one or the other.
Nevertheless, they all became Americans, Wisconsinites. They married, had children, owned land, worked and died in Wisconsin.
All the genealogical data I encountered on my research was included in my book "An American Family Since 1630" Volume I - Paternal Ancestors which is available from Amazon.com, also in Kindle version.
