Just Kessler, a farmer, and his wife Maria arrived from Lübeck at the port of Oranienbaum on 10 August 1766 aboard a ship under the command of Skipper Nikolaus Peter Pink.
They settled in the Volga German colony of Ober-Monjou on 3 August 1767 and are recorded there on the 1767 census in Household No. 55 along with their 6-month-old son Stephan.
In 1788, Stephan Kessler moved from Ober-Monjou to Wittmann. By 1798, he was living in Luzern. The 1798 census of Schönchen records that Anton Kessler from Ober-Monjou is working in Katharinenstadt.
The 1767 census records that Just Kessler came from the German village of Neukirch in the region of Nassau.
