There are two Koch families that arrived from Lübeck at the port of Oranienbaum on 8 August 1766 and settled in the Volga German colony of Huck on 1 July 1767.
(1) Widower Peter Koch and his children are recorded on the 1767 census of Huck in Household No. 13.
(2) Johann Melchior Koch and his new wife Johannette are recorded on the 1767 census in Huck in Household No. 14.
Both the Oranienbaum passenger list and the 1767 census of Huck record that these Koch families came from the German region of Isenburg.
