There are two Adam Kochs who originally settled in Norka.
The baptism of this Johann Adam Koch, son of Thomas Koch, is recorded in the parish register of Sterbfritz on 26 August 1731. He married Anna Catharina Bechtoldt, daughter of Conrad Bechtoldt, on 9 November 1752 in Roth. She had been born there and baptized in Gründau on 16 December 1725.
Six of their children were born in Roth: (1) Anna Elisabetha, born 11 August 1753; (2) Johann Casimir, born 16 February 1755; (3) Anna Maria, born 4 December 1757; (4) Maria Louisa, born 12 March 1760, died 15 March 1760; (5) Maria Elisabetha, born 19 March 1761; and (6) Johann Heinrich, born 16 January 1764.
Adam Koch and his family arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the pink Slon under the command of Lieutenant Sergey Panov.
They settled in the Volga German colony of Norka on 15 August 1767 and are recorded there on the 1767 census in Household No. 61.
Adam Koch, his wife Katharina, and children (Kasimir, age 18; Anna Maria, age 16) are recorded on the 1775 census of Norka in Household No. 46.
The Oranienbaum passenger list records that Adam Koch is a farmer while the 1767 census records that he is a craftsman (Handwerker). Both documents record that Adam Koch came from the German district of Isenburg.
