My grandmother Delphina Humler married William Frank Otto Blank in Milwaukee, Milwaukee, Wisconsin on April 3, 1897. Her mother was Amelia Erdman born 1857/1859 Germany. Amelia had a sister, Mathilda Erdman. My grandmother was born in Chicago, Il. in 1879. She spent her life here. I am trying to figure out why she married in Milwaukee??(Family?) Also I am trying to figure out the Erdman history. Amelia Erdman(my great-grandmother)married Joseph Humler in Chicago,Il. Nov.7, 1878. HELP!
