Johann Jakob Krug, a farmer, his wife Magdalena, and children (Louisa, age 17½; Johann [Jakob], age 13; Dorothea, age 10; Friedrika, age 4) arrived from Lübeck at the port of Oranienbaum on 18 June 1766 aboard the ship Die Perle under the command of Skipper Thomson.
The parents did not survive the journey between Oranienbaum and Saratov. The children settled in the Volga German colony of Kratzke on 7 August 1766 and are recorded there on the 1767 census in Household No. 9.
The Oranienbaum passenger list records that Johann Jakob Krug came from the German region of Pfalz.
