Johann Adam Essler, a farmer, arrived from Lübeck at the port of Oranienbaum on 22 July 1766 aboard the pink Lev under the command of Lieutenant Fyodor Fyodorov.
He settled in the Volga German colony of Pfeifer on 20 August 1767 and is recorded there on the 1767 census in Household No. 24.
The Oranienbaum passenger list identifies him as the brother-in-law of Johannes Stricker. The 1767 census records that he is the nephew of Johannes Stricker.
