I don't know if you are still active on this thread, but I think our family stories intersect.
My great great grandmother was Anna Louisa Medenwald (1813-1897) from Barskewitz, Kreis Saatzig, Pommern. She was married to (and widowed by) Ferdinand Jordan (1812-1846) and Friedrich Ewest 1820-c. 1850s) in Barskewitz and to August Gehloff in Kreis Filehne, Posen. Her daughter Friederike Wilhelmine (1844-1922) (my great grandmother), by Jordan married Wm. Christian Dahlman (1842-1915).
In the Barskewitz church yard there is a sign in German in memory of the German residents who died in the war put up by the Evangelical Church of Marienfliess.
If any of these people sound like your family members, let me know and we can swap information.
