Sebastian Schmidtlein, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 22 July 1766 aboard the pink Lev under the command of Lieutenant Fyodor Fyodorov.
His surviving son, Johann Michael, settled in the Volga German colony of Köhler on 21 August 1767 and is recorded there on the 1767 census in Household No. 61 with the Nikolaus Klein family. The 1767 census does not record a relationship between the Schmidtlein and Klein families.
The Oranienbaum passenger list records that Sebastian Schmidtlein came from the German region of Würzburg.
