Christoph Wagner, his wife Anna, and daughter Friederika (age 9-months) are recorded on the 1767 census of Kaneau in Household No. 25 along with an orphan Johann Gottlieb Wolfart (age 15). The 1767 census does not record a relationship between the Wagner and Wolfart families. They had settled in Kaneau on 7 June 1767.
In 1789, widow Johanna Sophia Wagner and her daughters moved from Kaneau to Bettinger.
The 1767 census records that Christoph Wagner came from the German region of Zerbst.
There are no known surviving male lines of this family among the Volga German colonies.
