Peter Röthler, a farmer, and his wife Anna 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. 31.
The 1767 census records that Peter Röthler came from the German village of Werheim in the Trier region.
There are no known surviving male lines of this family among the Volga German colonies.
