Konrad Dumrauf, a farmer, his wife Katharina, and children (Anna, age 9; Andreas, age 8; Maria, age 7) arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard a ship under the command of Skipper Heinrich Sager.
Konrad died after arriving in Russia and his widow Katharina remarried to Georg Popp who had arrived with them in Oranienbaum.
The combined Popp/Dumrauf families settled in the Volga German colony of Hölzel on 11 September 1767 and are recorded there on the 1767 census in Household No. 9.
The Oranienbaum passenger list records that Konrad Dumrauf came from the German region of Bamberg. Some documents have this surname listed as Dumerauf and Taumerauf.
