Konrad Wehrwein, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard an English frigate under the command of Skipper Adam Beerfeier.
They arrived in the Volga German colony of Nieder-Monjou on 3 August 1767 and are recorded there on the appendix to the 1767 census in Household No. 26 along with a note that they resettled to the colony of Näb in 1768.
In 1783, Kaspar Werwein and his family moved from Näb to Meinhard.
The 1767 census records that Konrad Wehrwein came from the German village of Krailshausen.
