Johannes Keller, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 18 June 1766 aboard the hooker Anna Catharina under the command of Skipper Adolph Scharpenberg.
They settled in the Volga German colony of Keller on 12 May 1767 and are recorded there on the 1767 census in Household No. 1. He is recorded there as the mayor (Vorsteher) of the colony and it is after him that the colony was named.
The 1767 census records that Johannes Keller came from the German village of Günsbach [believed to be Gimbsbach] in the Kurpfalz region.
