Jakob Diebach, a farmer, his wife Anna, and children (Heinrich, age 16½; Katharina, age 10) arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard the galliot Anna Katharina under the command of Skipper Johann Joachim Janson.
Widower Jakob and the children are recorded on the list of colonists being transported from Oranienbaum to Saratov in 1767.
Jakob and daughter Katharina are next recorded in Household No. 56 on the list of Beauregard recruits that is appended to the 1767 census - along with his new wife Margaretha.
In 1790, widower Jakob Deibach moved from Luzern to Schönchen.
The Oranienbaum passenger list records that Jakob Diebach came from the German region of Mainz. The 1767 census records that he came from the German area of Niederwald.
