Orphan Anna Katharina Heider (age 12) is recorded on an appendix to the 1767 census of Katharinenstadt in Household No. 3 along with the Peter Schönebeck family and a note that she relocated to the colony of Biberstein in 1768. The 1767 census does not record a relationship between the Heider and Schönebeck families.
The 1767 census does not record from where Anna Katharina Heider came.
There are no known surviving male lines of this family among the Volga German colonies.
