Michael Heinrich, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 31 July 1766 aboard a Russian ship under the command of Lieutenant Samuel Gibbs.
They settled in the Volga German colony of Pfeifer on 15 June 1767 where they are recorded on the 1767 census in Household No. 41.
Both the Oranienbaum passenger list and the 1767 census record that Michael Heinrich came from the German region of Mainz.
