Heinrich Heft, a farmer, and his wife Katharina settled in the Volga German colony of Balzer on 28 August 1765. They are recorded there on the 1767 census in Household No. 8 along with Valentin Habermann (age 16). The 1767 census does not record a relationship between the Heft and Habermann families.
The 1767 census records that Heinrich Heft came from the German region of Kurpfalz.
There is a Johann Heinrich Heft that immigrated to Denmark (Schleswig-Holstein) in 1762. The Eichhorns record that this might be the same man who later settled in Balzer.
In 1824, Heinrich Heft moved from Balzer to Dietel.
