Jakob Haas, a single farmer (age 19), and his sister Katharina (age 15) settled in the Volga German colony of Chasselois on 2 August 1766. They are recorded there on the 1767 census in Household No. 26 along with a note that their unnamed mother had died after immigrating to Russia.
Following the destruction of Chasselois, the Haas family relocated to the colony of Graf. In 1795, Johannes Haas moved from Graf to Mariental.
The 1767 census records that Jakob Haas came from the German village of Seret in the Lothringen region of France.
