Johann[es] Koch, his wife Anna, and his brothers [not sons] (Johann, age 16; Martin, age 8) arrived from Rewal at the port of Oranienbaum aboard the pink Lopamink under the command of Lieutenant Kryukov.
They settled in the Volga German colony of Warenburg on 12 May 1767 and are recorded there on the 1767 census in Household No. 16.
In 1788, Johann Martin Koch moved from Warenburg to Jost.
The Oranienbaum passenger list records that Johann[es] Koch was a farmer from the German region of Oldenburg. The 1767 census records that Johannes Koch was a gardner (Gärtner) from the German village of Großenkneten.
