Christoph Kummer, a farmer, and his wife Elisabeth arrived from Lübeck at the port of Oranienbaum on 10 August 1766 aboard a ship under the command of Skipper Nikolaus Peter Pink.
They settled in the Volga German colony of Boisroux on 3 August 1767 and are recorded there on the 1767 census in Household No. 87 along with orphan Christoph Handorf (age 9). The 1767 census does not record a relationship between the Kummer and Handorf families.
In 1787, widow Anna Elisabeth Kummer moved from Boisroux to marry Mattias Riel in Beauregard. She also took her children.
The Oranienbaum passenger list records that Christoph Kummer came from the German region of Sachsen (Saxony). The 1767 census records that he came from the German village of Halle in the Brandenburg region.
