This is a long shot... My husband's family is from Chicago. His Grandmother's maiden name was Wolff. Her father's name was Paul Theodor Wolff, b. 27 Oct 1865, Germany. He married Antonia Anna Zimmerman in Chicago 1892. He was one of 9 children born to August Wolff and Wilhelmina Bettin. I have very little information, as the older generations have passed away leaving no clues.
