Georg Hartmann, a farmer, and his family including stepchildren arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard the snow-brig Der Merkur under the command of Skipper Johann Heinrich Abelmann.
They settled in the Volga German colony of Sewald on 20 August 1767 and are recorded there on the 1767 census in Household No. 31.
The Oranienbaum passenger list records that Georg Hartmann came from the German Pfalz region while the 1767 census records that he came from Pischeldorf.
