Nikolaus Siebert, a farmer, and his wife Anna Maria arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard a ship under the command of Skipper Heinrich Sager.
They settled in the Volga German colony of Semenovka on 24 July 1767 and are recorded there on the 1767 census in Household No. 39.
Both the Oranienbaum passenger list and the 1767 census record that Nikolaus Siebert came from the German region of Hanau.
