Franz Bach, a farmer, his wife Margaretha, and his brother Nikolaus settled in the Volga German colony of Chasselois on 2 August 1766. They are recorded there on the 1767 census in Household No. 25. A note on the 1767 census indicates that Margaretha later married the brother Nikolaus.
Following the destruction of Chasselois, the Bach family relocated to the colony of Louis. In 1787, widow Appolonia Bach and her daughter moved from Louis to Ober-Monjou.
The 1767 census records that Franz Bach came from the German village of Saarlouis in the German region of Lothringen (France).
