Christoph Eichner, a farmer, and his wife Johanna are recorded on an appendix to the 1767 census of Paulskaya in Household No. 43 along with a note that they settled in the colony of Biberstein in 1768.
The 1767 census records that Christoph Eichner came from the German village of Reichenbach.
There are no known surviving male lines of this Eichner family among the Volga German colonies.
