Johannes Pachtrech, a baker (Bäcker), and his wife Josephina arrived from Lübeck at the port of Oranienbaum on 30 May 1766 aboard the pink Lopamink under the command of Lieutenant Kryukov.
They settled in the Volga German colony of Leitsinger on 12 May 1767 and are recorded there on the 1767 census in Household No. 28.
The 1767 census records that Johannes Pachtrech came from Vienna, Austria.
There do not appear to be any surviving male descendants of this family so the surname does not continue among the Volga German colonies.
