The parish register of Büdingen records on 7 May 1766 the marriage of Johannes Marquard, a widower from Eckertshausen, and Anna Maria Stephan, a widow from Eckertshausen.
Johann Marquardt, a farmer, his wife Anna Maria, and children (Johann Michael, age 14; Johann Jakob, age 12; Johann, age 9½) arrived from Lübeck at the port of Oranienbaum on 29 August 1766 aboard the ship Apollo under the command of Skipper Detlov Merberg.
Son Michael (age 17) settled in the Volga German colony of Norka and is recorded there on the 1767 census in Household No. 50 living with the Engelhard Berger. A relationship between the Berger and the Marquardt families is not recorded on the 1767 census.
Michael Marquardt is recorded on the 1775 census of Norka in the Supplement (No. 8).
Son Michael is recorded on the 1798 census of Kutter in Household No. Kt19.
Both the Oranienbaum passenger list and the 1767 census record that this Marquardt family came from the German district of Isenburg.
