Widow Katharina Knaub and her children (Katharina Friedrika, age 17½; Johann Konrad, age 14; Ludwig, age 12; Johann Heinrich, age 10; Philipp Peter, age 8; Magdalena, age 1½) arrived from Lübeck at the port in Oranienbaum on 8 August 1766 aboard the snow-brig Der Merkur under the command of Skipper Johann Heinrich Abelmann.
On the same ship arriving in Oranienbaum were Valentin Traub and his wife, Eva. Eva died at some point during the journey to the colonies, and Valentin married the widow Katharina Knaub.
Valentin, Katharina, and her three surviving children (Konrad, Ludwig, & Philipp) settled in the Volga German colony of Kautz on 29 July 1767. They are recorded there on the 1767 census in Household No. 15.
In 1788, Philipp Peter Knaub moved from Kautz to Balzer.
Johann Tobias Knaub, son of Philipp Knaub from Kautz, was born 10 November 1889 in Grimm. He died in November 1918 in Sterling, Colorado.
The 1767 census records that Katharina Knaub came from the German village of Grosshausen near Darmstadt.
