Hans Hartmann, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 3 June 1766 aboard the galliot Adler under the command of Skipper Paul Adolph Drath.
They settled in the Volga German colony of Dinkel on 27 July 1767 and are recorded there on the 1767 census in Household No.37.
The 1767 census records that he came from the town of Bulwitz in Sweden. This is believed to be Ballwitz which at the time was located in Swedish Pomerania.
