Johann Christoph Bender, a farmer (Ackerbauer), and his wife settled in the Volga German colony of Kratzke on 8 May 1767. They are recorded there on the 1767 census in Household No. 40.
The 1767 census records that Johann Christoph Bender came from the German village of Neilos [Cyrillic: Наилос] in the Württemberg region. Dr. Igor Plehve's translation of the 1767 census records this location as Nauleis near Wittenberg.
