Johannes Knatz, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 12 September 1766 aboard the English frigate Love & Unity under the command of Skipper Thomas Fairfax.
They settled in the Volga German colony of Philippsfeld on 3 August 1767. They are recorded there on the 1767 census in Household No. 18.
In 1786, Johann Knatz and his family moved from Philippsfeld to Fischer. In 1797, widow Anna Marta Knatz and her son moved from Fischer to Urbach. Martin Knatz and his family also moved to Urbach in 1797.
