Johannes Leinhardt, a farmer, and his wife Albertina are recorded on an appendix to the 1767 census of Boisroux in Household No. 25 along with a note that they relocated to the colony of Orlovskaya in 1768.
The 1767 census records that Johannes Leinhardt came from the German village of Beseke [?].
There are no known surviving male lines of this Leinhardt family among the Volga German colonies.
