Johann Konrad Zisch, son of Johannes Zisch & Anna Maria Kraft, was born on 22 May 1739 in Gelnhausen, northeast of Hanau.
Johann Konrad Zisch, a farmer, his wife Katharina, and children (Maria, age 22; Konrad, age 19; Martin, age 15; Johann [Christian], age 13) arrived from Lübeck at the port of Oranienbaum on 19 July 1766 aboard a ship under the command of Skipper Jacob Bauer. They settled in the Volga German colony of Schwab on 8 July 1767 and are recorded there on the 1767 census in Household No. 11.
By 1798, sons Konrad and Martin had moved to Galka and the widow of son Christian and their children were living in Grimm.
Both the Oranienbaum passenger list and the 1767 census record that Johann Konrad Zisch came from Gelnhausen.
