Wolfgang Dreher, a single baker (Bäcker), arrived from Lübeck at the port of Oranienbaum on 20 May 1766 aboard the Russian galliot Katharina Eleonora under the command of Skipper Peter Röder.
He settled in the Volga German colony of Kamenka on 12 February 1767 and is recorded there on the 1767 census in Household No. 21 along with his new wife Katharina.
The Oranienbaum passenger list records that Wolfgang Dreher came from the German region of Böhmen (Bohemia) while the 1767 census records that he came from the German village of Straubing.
