There are two Mohr families that settled in the Volga German colony of Rohleder on 14 July 1766. Their relationship to each other is not recorded on the 1767 census.
(1) Katharina Mohr (age 19) is recorded on the 1767 Rohleder census in Household No. 29 along with her mother and stepfather, Nikolaus Junker.
(2) Nikolaus Mohr, a farmer, and his wife Anna Maria (from the German region of Mainz) are recorded on the 1767 Rohleder census in Household No. 40. In 1793, Nikolaus Mohr moved from Rohleder to Luzern.
The 1767 census records that Nikolaus Mohr came from the German village of Rastatt in the Baden-Durlach region.
