Johann Gottlieb Kettler (age 17) and his sister Sophia (age 16), children of the deceased Johann Kettler, settled in the Volga German colony of Kamenka on 6 July 1765.
They are recorded there on the 1767 census in Household No. 2 along with the Johann Bauer family. A note on the 1767 census records that they are actually living with the Johann Georg Plattner family. The 1767 census does not record a relationship between the Kettler, Bauer, and Plattner families.
The 1767 census records that Johann Gottlieb Kettler came from Switzerland.
