Sounds like you are looking for information about German colonists in Poland from before the war. They were ethncially German, but living in Poland. There are a few websites for this purpose. Prussian websites, Eastern European websites.
Schneider could be as well a Jewish surname (because Germans weren't very clever when they decided they had to name all the Polish Jews, you were a tailor [= "Der Schneider" in German], a profession not uncommon among Jews, you got yourself the name Schneider :)
With the name Adam he could have been any ethnical group
