Johann Gerhardt, a farmer, and his wife Katharina arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard a ship under the command of Skipper Wiebe Heinrichson.
They settled in the Volga German colony of Bangert on 26 June 1767. Johann died there on 25 August 1767 and Katharina remarried to the widower Egidius Huber. They are recorded on the 1767 census of Bangert in Household No. 27 along with Johann Gerhardt's newborn son, Johannes (3 months old).
The Oranienbaum passenger list records that Johann Gerhardt came from the German district of Darmstadt.
