There are two Gaus families [erroneously recorded in some records as Kaust] that settled in the Volga German colony of Fischer on 7 July 1766. They are probably father and son, although this relationship is not recorded on the 1767 census.
(1) Johannes Kaust [sic] (age 50), a farmer, and his second wife Christina are recorded on the 1767 census of Fischer in Household No. 26 along with his children by his 1st wife (Katharina, age 16; Georg, age 14; Alexander, age 12) and those by his 2nd wife (Johann Fein, age 6; Johann Samuel, age 4). Also living with them are Christina's children by her previous marriage (Jakobina Grauer, age 21; Hans Christian Grauer, age 11). The 1767 census records that Johannes Kaust came from the German village of Paulbrunn in the Württemberg region.
(2) Michael Kaust [sic] (age 20), a farmer, is recorded on the 1767 census in Household No. 24 along with his wife Margaretha Katharina and their 4-month-old son Johann Wilhelm. The 1767 census records that Michael Kaust [sic] came from the German village of Stuck in the Wittenburg [Württemberg?] region.
