As of Jan 2012 I have not yet determined where "Neuendorf" is in modern Poland or Germany. Other places for this family include Stettin & Stargard that I have positively identified as well as Strwsow and I have not. Below is a map showing possible places for Stresow and Neuendorf in relation to Stettin & Stargard. There seem to be 3 possibilities for each.

I have not ruled out the sites near Gdansk even though they are so far from Stettin & Stargard as there is a family rumor that Hermann Heidemann used to say that he was from Gdansk.

These places were found on Wikipedia:
