Rudolph Lerch, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 15 September 1766 aboard the galliot Adler under the command of Skipper Paul Adam Drath.
They settled in the Volga German colony of Schäfer on 30 August 1767 and are recorded there on the 1767 census in Household No. 53.
Both the Oranienbaum passenger list and the 1767 census record that Rudolph Lerch came from the German region of Zweibrücken.
