Kaspar Koch and his wife Maria Barbara arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the pink Novaya Dvinka under the command of Lieutenant Perepechin.
They settled in the Volga German colony of Hildmann on 20 June 1767 and are recorded there on the 1767 census in Household No. 31.
The Oranienbaum passenger list records that Kaspar Koch was a farmer while the 1767 census records that he was a cobbler (Schuhmacher). The 1767 census records that Kaspar Koch came from the German village of Heiligenstadt in the Mainz region.
There are no known surviving male lines of this Koch family among the Volga German colonies.
