Heinrich [Balzer] Roth (age 13) and his brothers (Johann, age 9; Georg, age 5) arrived from Lübeck at the port of Oranienbaum on 25 July 1766 aboard the snow-brig Maria Sophia under the command of Skipper Johann Bauer along with their mother and stepfather, Ludwig Braun.
They settled in the Volga German colony of Warenburg on 12 May 1767 and are recorded there on the 1767 census in Household No. 88.
The 1767 census records that Heinrich Balzer Roth came from the German village of Wintersdorf in Sachsen (Saxony).
