I have come to a dead end looking for our Herzbergs. All I know is that my husband's grandmother was Louisa Mary Herzberg born November 14, 1871 in Germany. I am not sure what part. She came to the United States and the St. Louis, MO area about 1891. She married John Charles Stahl soon after that. I know she had a brother named Henry and his wife named Anna that lived in that area.
