Three Ruhl families arrived from Lübeck at the port of Oranienbaum on 13 September 1766 aboard the hooker Die Jungfer Dietrika under the command of Skipper Christian Korsholm.
Each of them settled in the Volga German colony of Köhler on 21 August 1767. Their relationship to each other is not recorded on the 1767 census.
(1) Zacharius Ruhl (age 40), a weaver (Weber) and his family are recorded on the 1767 census of Köhler in Household No. 30.
(2) Lorenz Ruhl (age 34), a farmer and his wife Katharina are recorded on the 1767 census of Köhler in Household No. 33.
(3) Widower Philipp Ruhl (age 34), a farmer, is recorded on the 1767 census of Köhler in Household No. 34.
The 1767 census records that all three of these Ruhl families are from the German village of Herbstein in the Fulda region.
