Johann Dehler, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard a ship under the command of Skipper Johann Gottfried Seelender.
They settled in the Volga German colony of Dehler on 1 July 1767 and are recorded there on the 1767 census in Household No. 1 along with a note that Johann Dehler is the colony's mayor (Vorsteher). It is after Johann Dehler that the colony received its name.
The 1767 census records that Johann Dehler is from the German village of Wernborn in the region of Kurmainz.
