Mattias Wahn, his wife Katharina, and children (Louisa, age 5; Johann, age 1½) arrived from Lübeck at the port of Oranienbaum on 15 September 1766 aboard a ship under the command of Skipper Franz Nikolaus Schröder.
Mattias Wahn, a miller (Müller), and his wife Katharina are recorded on an appendix to the 1767 census of Beauregard in Household No. 24 along with a note that they settled in the Volga German colony of Biberstein in 1768.
The 1767 census records that Mattias Wahn came from the German village of Schwabenheim. [This is believed to be Pfaffen-Schwabenheim because a number of other Volga German families came from the neighboring village of Sprendlingen.]
