Johann Heinrich Heinz arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the pink Novaya Dvinka under the command of Lieutenant Perepechin.
He settled in the Volga German colony of Grimm and is recorded there on the 1767 census in Household No. 78 along with stepson Wilhelm Klein, son of the deceased Wilhelm Klein (age 15), and orphans Katharina Schwartz (age 15) and her brother Johann Valentin Schwartz (age 12). The 1767 census does not record a relationship between the Heinz and Schwartz families.
Heinrich Heinz and his family recorded on the 1775 census of Grimm in Household No. 153 where both Wilhelm Klein and Valentin Schwartz are recorded as stepsons.
In 1788, Heinrich Heinz and his family moved from Grimm to Sarepta.
The Oranienbaum passenger list records that Johann Heinrich Heinz was a mechanic while the 1767 census records that he was a craftsman (Handwerker).
Both the Oranienbaum passenger list and the 1767 census record that Johann Heinrich Heinz came from the German region of Zweibrücken.
