Georg [Andreas] Nieslein, a single man, arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard a ship under the command of Skipper Heinrich Sager.
He married Ursula, the widow of Thomas Herbstsommer. They settled in the Volga German colony of Hölzel on 11 September 1767 and are recorded there on the 1767 census in Household No. 10 along with his stepson, Johannes Herbstsommer and Michael Loch (age 7), the surving son of Johannes Loch. The 1767 census does not record a relationship between the Nieslein and Loch families.
The 1767 census records that Andreas Niesslein came from the German village of Portljaes [?] in the Bamberg region.
