Konrad Neff, a farmer, and his wife Katharina arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard an English frigate under the command of Skipper Adam Beerfeier.
They settled in the Volga German colony of Nieder-Monjou on 3 August 1767 and are recorded there on the 1767 census in Household No. 81.
In 1786, Konrad Neff moved from Nieder-Monjou to the Caucasus.
