Nikolaus Zahn, a farmer, his wife Johanna, and children (Johann [Michael], age 16; Anna [Margaretha], age 15; Anna [Elisabeth], age 11; Johann, age 5) arrived from Lübeck at the port of Oranienbaum on 15 September 1766 aboard a ship under the command of Skipper Franz Nikolaus Schröder.
They are recorded on an appendix to the 1767 census of Beauregard in Household No. 6 along with a note that they relocated to the Volga German colony of Biberstein in 1768.
In 1771, Louisa Holtz moved from Boisroux and married Ludwig Zahn in Biberstein. She took her son Gottfried with her.
