They settled in the Volga German colony of Kraft on 18 August 1767 and are recorded there on the 1767 census in Household No. 56. The Oranienbaum passenger list records that Johann Kaspar Völker came from the German region of Isenburg while the 1767 census records that he came from the German village of Burgsinn.
