Conrad Lauber (age 19) and his sisters (Eleonore, age 17; Anna Maria, age 14) are recorded on the 1767 census of Reinhard in Household No. 20 along with their stepfather Paul Heinrich Rolof.
The 1767 census does not record from where the Lauber siblings came.
There are no known surviving male lines of this Lauber family among the Volga German colonies.
