Johann Christoph Arnhold, a farmer, and his wife Katharina Barbara settled in the Volga German colony of Rosenheim on 15 March 1766. They are recorded there on the 1767 census in Household No. 57.
The 1767 census records that Johann Christoph Arnhold came from the village of Sackfeld in Austria.
The Eichhorns record that this family could have moved to Denmark (Schleswig-Holstein) before immigrating to Russia. However, the family that they have identified came from the Württemberg region in Germany which doesn't match what is recorded in the 1767 census of Rosenheim.
