Johann Georg Schwartz, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 30 May 1766 aboard the pink Lopamink under the command of Lieutenant Kryukov.
Those who survived the journey settled in the Volga German colony of Leitsinger on 12 May 1767. They are recorded on the 1767 census in Household No. 23 along with son Sebastian, his new wife, and his stepson, Johann Adam (surname not recorded).
The 1798 census of Neu-Kolonie records a couple of orphaned Schwartz children, and because Leitsinger was destroyed and many survivors resettled to Neu-Kolonie, it is presumed that they are descendants of Sebastian Schwartz.
The 1767 census records that Sebastian Schwartz came from the German village of Fraunseck in the Pfalz-Neuburg region.
