Johann Fleischer, a pharmacist's apprentice (Apotheker-Lehring), and his wife Anna arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard an English frigate under the command of Skipper Adam Beerfeier.
They settled in the Volga German colony of Katharinenstadt on 3 August 1767. He is recorded there on an appendix to the 1767 census of Katharinenstadt in Household No. 4 along with a new wife Sophia Binner and a note that they settled permanently in Katharinenstadt in 1768.
The 1767 census records that Johann Friedrich (Gottlieb) Fleischer came from the German village of Stals bei Taugemüdung in Prussia.
