I am looking for Koehler/Kohler/Köhler family from Pommerania.I know father's name was Karl (1807-1880).There were at least four sons - Wilhelm (1833-1911), Ernest Frederick (1839-1926), Franz (1841-?) and August (1842-1923) and a daughter who was killed in some kind of a fire in Germany.Wilhelm, Ernest & Franz came to the US.August stayed in Germany and had a son Erich and a daughter Elsa. The last we heard the family was in Berlin. Does any of this fit with the family you are looking for? Thanks.
