Balthasar Ellang [sic], a farmer, his wife Katharina, and daughter Kunigunda (age ½) arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard a ship under the command of Skipper Heinrich Sager.
Balthasar Ehrler and his wife Cathrina are recorded on the list of colonists being transported from St. Petersburg to Saratov in 1767.
Balthasar Erler, a farmer, and his wife Katharina settled in the Volga German colony of Rohleder on 28 August 1767. They are recorded there on the 1767 census along with the single man Justus Gorf. The 1767 census does not record a relationship between the Ehrler and Gorf families.
In 1780, Sebastian Ehrler moved from Rohleder to Kamenka.
Both the Oranienbaum passenger list and the 1767 census record that Balthasar Ehrler came from the German region of Würzburg.
There are no known surviving male lines of this family among the Volga German colonies.
