Johannes Dechant, a cabinet maker (Tischler), 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 settled in the Volga German colony of Ober-Monjou on 23 July 1767 and are recorded there on the 1767 census in Household No. 64.
In 1788, Johann Georg Dechant moved from Ober-Monjou to Wittmann.
The 1767 census records that Johannes Dechant came from the German village of Höchst in the district of Hanau.
