Valentin Markus, a single farmer, arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard a pink under the command of Lieutenant Moisey Davydov.
He settled in the Volga German colony of Krasnoyar on 20 July 1767 and is recorded there on the 1767 census in Household No. 38 along with his new wife Barbara Katharina.
Both the Oranienbaum passenger list and the 1767 census record that Valentin Markus came from the German village of Schlitz.
