Can anyone help me please?

My great-grandfather, his siblings and parents came to the US from Stuchow, Prussia (Pomerania) in the mid-1880s. I am trying to locate where I can find further records about the family of Bartelt that came from there. From Goggling I think I have learned that Stuchow is now named Stuchowo, but does anyone know who I can contact to learn more information.

I already checked Family Search (LDS) to see if they have records on microfilm and I did not find anything.

Thank you in advance for assistance.
