Martin Eberhardt and his family immigrated to Russia. The only surviving member of the family appears to be Magdalena Eberhardt (age 8) who is recorded on the 1767 census of Norka in Household No. 90 living with the Johannes Kleiber family. The relationship between the Eberhardt and Kleiber families is not recorded on the 1767 census.
