Conrad Wilhelm Kontschuch, son of Augustini Kontschuch, was born in Ortenberg (near Büdingen) on 20 February 1707. He married Anna Elisabeth Wendel, daughter of Johann Conrad Wendel, on 30 November 1730. They had one daughter: Anna Elisabeth, who died on 7 March 1738. Conrad Wilhelm then married Anna Barbara Blum, daughter of Johannes Blum, on 4 September 1738. They had three children: (1) Georg Christoph, born 6 January 1740; (2) Johann Daniel, born 23 May 1742; and (3) Anna Margaretha, born 15 January 1745. Anna Barbara died on 22 July 1762 and Georg Christoph married a third time to Maria Catharina Krahl on 1 March 1763. They had one son: Johann Daniel, born 13 October 1763.
The surviving members of this Konschuh family immigrated to Russia and arrived from Lübeck at the port of Oranienbaum on 13 September 1766 aboard the galliot Die Perle under the command of Skipper Thomson. They settled in the Volga German colony of Yagodnaya Polyana on 16 September 1767. The 1767 census of Yagodnaya Polyana records Widower Konrad Wilhelm Konschuh in Household No. 4 and son Christoph and his family in Household No. 2.
The 1767 census records that both of these Konschuh families came from the German village of Ortenberg near Hanau.
