Christoph Kaufmann and his wife Maria arrived from Lübeck at the port of Oranienbaum on 22 July 1766 aboard the pink Lev under the command of Lieutenant Fyodor Fyodorov.
Christoph settled in the Volga German colony of Pfeifer on 15 June 1767 and is recorded there on the 1767 census in Household No. 26 along with his new wife Barbara.
The Oranienbaum passenger list records that Christoph Kaufmann was a tailor from the German region of Pfalz. The 1767 census records that he was a farmer from the German town of Mannheim.
There are no known suviving male lines of this Kaufmann family among the Volga German colonies.
