Ersen Lambert, a farmer, and his wife Wilhelmina are recorded on an appendix to the 1767 census of Nieder-Monjou in Household No. 43 along with a note that they relocated to the colony of Katharinenstadt in 1768.
The 1767 census records that Ersen Lambert came from the German village of Fenn.
There are no known surviving male lines of this family among the Volga German colonies.
