Sebastian Karl and his wife Anna 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.
They are recorded on an appendix to the 1767 census of Beauregard in Household No. 72 and eventually settled in the Volga German colony of Boisroux.
In 1786, Sebastian Karl and his wife moved from Boisroux to the Caucasus.
The Oranienbaum passenger list records that Sebastian Karl was a tailor from the German region of Hannover. The 1767 census records that Sebastian Karl was a farmer from the German village of Haldorf in the Hannover region.
