I think I'm related to the Emma you are looking for. IF: She was 1 of 9 children born to Augusta Oestmann and Frank Kummerow (in Chicago) married 1879. the others are Martin, Lizzie, Gustie, Addie, Frank, George, Tillie and Fred. My records show she married a Goldbeck.
Augusta was born in Chicago 1859, Daughter of Jacob Oestmann (1831 - 1913), and Fenne A. Franzen (1832 - 1902). Both born in Germany.
