Johannes Kratz, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard the galliot Anna Catharina under the command of Skipper Johann Joachim Janson.
They arrived in the Volga German colony of Boisroux on 3 August 1767 and are recorded there on an appendix to the 1767 census in Household No. 3 along with a note indicating that they relocated to the colony of Basel in 1768.
The Oranienbaum passenger list records that Johannes Kratz came from the German region of Darmstadt while the 1767 census records that he came from the German village of Zelbig.
