Johann Dittmeier, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 29 August 1766 aboard the ship Apollo under the command of Skipper Detlov Merberg.
They settled in the Volga German colony of Pfeifer on 20 August 1767 and are recorded there on the 1767 census in Household No. 52.
Both the Oranienbaum passenger list and the 1767 census record that Johann Joseph Dittmeier came from the German region of Würzburg.
