In addition to Baby Boy Knopf, William and Pauline had one other child that did not survive, as indicated on the 1900 census data.
In the 1910 U.S. Census, one of William's sons is enumerated with the name "Bernard". Living knowledge says that this is a mistake, as we have no ancestor named Bernard. In this case, Bernard refers to son Benjamin, who is otherwise not listed there.
William and brother Gustav are both enumerated on the 1920 and 1930 census pages, since they only lives a few doors down from each other.
William, Pauline, and Oswald took a trip in 1911 to Poland to get their relatives, Julius and Christine Netz, whom they sponsored for immigration to America. Christine Netz was a sister to William's wife, Pauline. Other pages of that ship's manifest show the Netz family. Also included in that voyage is Anna Rossol, whose destination is listed as visiting her "uncle" William Knopf. How can William be Anna's uncle? This is a mystery I have found no explanation for.
