I am looking for some help on a town called Tangen near Buetow.Any and all info would greatly be appreciated, My grandfather Otto Poschke was born in 1884 there. His father's name was August and his mother's name was Bertha Mueller. Would there be any surviving church records for this town? If not, is there someone in the government I could contact for any records on the family? attached is a map of the town.
