Samuel Jerke, a cobbler (Schuhmacher), and his wife Rosina arrived from Lübeck at the port of Oranienbaum on 18 June 1766 aboard the ship Mann und Frau under the command of Skipper Daniel Berg.
They settled in the Volga German colony of Jost on 5 July 1767 and are recorded there on the 1767 census in Household No. 6.
The Oranienbaum passenger list records that Samuel Jerke came from the German region of Anhalt. The 1767 census records that he came from the German village of Lebbin in the Brandenburg region.
