My grand-mother Erna Boldewahn spoke German and English. My mother remembers sitting at the kitchen table with her mother and her mother’s cousin, Mary Schoblaski listening to them speak German.
- The dialect was most likely a variation of Platt Deutsch (Low German)
- Wikipedia says that the inhabitants of Pommern (Northern Prussia) spoke the Ostpommersch (East Pomeranian) dialect
- which is a variation of East Low German
The language has mostly died out, but is still spoken in Brazil where many Prussians emigrated to in the 1800s.
