Bartholomaeus Manz, a farmer, and his wife Helena arrived from Lübeck at the port of Oranienbaum on 8 August 1766.
They settled in the Volga German colony of Köhler on 10 August 1767 and are recorded there on the 1767 census in Household No. 18 along with the orphaned Simon Siefert (age 12), son of the deceased Jakob Siefert. The 1767 census does not record a relationship between the Manz and Siefert families.
The Oranienbaum passenger list records that Bartholomaeus Manz came from Luxembourg while the 1767 census records that he came from the German region of Fulda.
