Johann Knopf, a farmer, his wife Agness, and children (Walpurga, age 16½; Nikolaus, age 10½; Franz, age 1) arrived from Rewal at the port of Oranienbaum on 30 May 1766 aboard the pink Lopamink under the command of Lieutenant Kryukov.
They settled in the Volga German colony of Keller on 12 May 1767 where surviving daughter Walpurga is recorded on the 1767 census in Household No. 37 along with the Mathias Hoffmann family. The 1767 census does not record a relationship between the Hoffmann and Knopf families.
Following the destruction of Keller, the Knopf family resettled to the colony of Neu-Kolonie. In 1790, Jakob Knauf moved from Neu-Kolonie to Brabander.
The Oranienbaum passenger list records that Johann Adam Knopf came from the German region of Bamberg.
