My great-grandfather was THEODOR ALBERT GUSTAV DROMER. He was born January 22, 1861 in Potsdam and he died May 29, 1951 in Russdorf. I am told he had two brothers but no one knows their names or anything else about them. They were the sons of AUGUST FRIEDRICH WILHELM DROMER (1822-?) and his wife, FRIEDRIKE AUGUSTE WASSERMAN (1826-?) of Brandenburg. Does anyone have any information about this family?
