Johann Georg Marklof, a single farmer, arrived from Lübeck at the port of Oranienbaum on 10 August 1766 aboard a ship under the command of Skipper Nikolaus Peter Pink.
He married widow Anna, and they settled in the Volga German colony of Nieder-Monjou on 3 August 1767. They are recorded there on the 1767 census in Household No. 30 along with Anna's daughter, Anan Margaretha (age 10).
Both the Oranienbaum passenger list and the 1767 census record that Johann Markolf came from the German region of Darmstadt.
