Widow Maria Horn and her children (Andreas, age 12; Christoph, age 10; Johanna, age 5; Maria, age 3) arrived from Lübeck at the port of Oranienbaum on 18 June 1766 aboard the ship Mann und Frau under the command of Skipper Daniel Berg.
They settled in the Volga German colony of Jost on 5 July 1767. Maria remarried to Johann Jakob Arndt. Her children are recorded on the 1767 census of Jost in Household No. 8 along with step-father Johann Jakob Arndt.
The Oranienbaum passenger list records that Maria Horn came from the German region of Dessau.
