Johann Adam Köhler, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the Russian galliot Strelna under the command of Lieutenant Sornev.
They settled in the Volga German colony of 17 August 1767 and are recorded there on the 1767 census in Household No. 87.
In 1790, Johann Wilhelm Keller moved from Huck to Norka.
Both the Oranienbaum passenger list and the 1767 census record that Johann Adam Köhler came from the German region of Isenburg.
