Widow Dorothea Lehmann and her son David arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard the snow-brig Der Merkur under the command of Skipper Johann Heinrich Abelmann.
Dorothea remarried to Gottfried Herbst and settled in the Volga German colony of Urbach on 13 July 1767. However, she, too, must have died because the 1767 census of Urbach records that Gottfried Herbst's wife is Anna Katharina and that they are in Household No. 5 along with his stepson David Lehmann.
The Oranienbaum passenger list records that Dorothea Lehmann came from the German region of Prussia.
