Johann Oberst, a farmer, and his wife Anna 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. He is recorded there on the 1767 census in Household No. 41 as a single man.
