Adam Geist, a farmer, and his wife Dorothea Elisabeth arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the pink Novaya Dvinka under the Command of Lieutenant Perepechin.
They settled in the Volga German colony of Pfeifer on 20 August 1767 and are recorded there on the 1767 census in Household No. 98 [under the surname Heiss].
Dorothea died and Adam remarried to Maria Susanna Trapp, widow of Gerhardt Froshchauer of Köhler. Adam had at least three children: Maria, Matthias, and Jakob. At least the first two had to have been the result of the first marriage, born in Pfeifer.
His descendants moved to the colony of Köhler.
The Oranienbaum passenger list records that Adam Geist came from the German region of Mainz while the 1767 census records that Johann Adam Geist came from the German region of Orb.
