Jakob Kaufmann, a farmer, his wife Anna, and son Oswald arrived from Lübeck at the port of Oranienbaum on 8 August 1766. Later documents confirm Oswald's surname as Niederhausen, so perhaps he is actually a step-son of Jakob Kaufmann. The parents died after arrival in Russia.
Son Oswald Kaufmann [actually Niederhausen] settled in the Volga German colony of Huck on 1 July 1767 and is recorded there on the 1767 census in Household No. 1 along with the family of Johannes Huck.
The 1767 census does not record a relationship between the Kaufmann/Niederhausen and Huck families.
