There are two Adam Kochs who originally settled in Norka.
This Adam Koch and his family arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the pink Slon under the command of Lieutenant Sergey Panov.
They settled in the Volga German colony of Norka on 15 August 1767 and are recorded there on the 1767 census in Household No. 61.
The Oranienbaum passenger list records that Adam Koch is a farmer while the 1767 census records that he is a craftsman (Handwerker). Both documents record that Adam Koch came from the German district of Isenburg.
