Johann Knaub, a farmer, and his wife Sara immigrated to Denmark (Schleswig-Holstein), arriving in the city of Schleswig on 20 May 1761.
\They deserted the Danish colonies on 20 March 1766 and joined the migration to Russia.
Johann Knaub and his family arrived from Lübeck at the port of Oranienbaum on 3 June 1766 aboard the galliot Adler under the command of Skipper Paul Adolph Drath.
They settled in the Volga German colony of Schäfer on 25 May 1767 and are recorded there on the 1767 census in Household No. 46 along with Johann's new wife and her children (surname Ertel).
In 1788, Heinrich Knaup moved from Schäfer to Mariental.
Both the Oranienbaum passenger list and the 1767 census record that Johann Knaub came from the German region of Darmstadt. The Eichhorns record that Johann Knaub came from the German Landgrafschaft of Hessen-Darmstadt.
