Widower Johann Christoph Weigandt, a farmer, and his daughter Anna Maria arrived from Lübeck at the port of Oranienbaum on 13 September 1766 aboard the Russian galliot Citadel under the command of Midshipman Grigory Bukharin.
They settled in the Volga German colony of Pfeifer on 20 August 1767 and are recorded there on the 1767 census in Household No. 68.
The 1767 census records that Christoph Weigandt came from the German village of Groß Steinum in the Mainz region.
