Heinrich Hoffmann, a single farmer, and his brother Andreas, also a single farmer, arrived from Lübeck at the port of Oranienbaum on 4 July 1766 aboard the ship Die Neue Freiheit von Bremen under the command of Skipper Steingrawer.
They settled in the Volga German colony of Warenburg on 12 May 1767 and are recorded there on the 1767 census in Household No. 154 along with Heinrich's new wife Anna Elisabeth.
In 1796, Heinrich Hoffmann and his family moved from Warenburg to Kratzke.
The 1767 census records that Johann Heinrich Hoffmann came from the German village of Niederdorfelden in the Nassau region.
