My great-grandfather was Theodor Albert Gustav DROMER. He was born January 22, 1861 in Potsdam, Germany and he died May 29, 1951. He had 2 brothers. I do not know their names or any other information about them. Their parents' names were August Friedrich Wilhelm DROMER (1822-????) and Friederike Auguste WASSERMANN (1826-????). Does anyone have any information about this family?
