Konrad Lehmann and his wife Katharina 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.
Konrad and his new wife Anna are recorded in Household No. 10 on an appendix to the 1767 census of Paulskaya. They settled in the Volga German colony of Kind.
In 1770, widow Katharina Lehmann and her son moved from Katharinenstadt to Susannental.
The Oranienbaum passenger list records that Konrad Lehmann was a miller from the German region of Hessen. The 1767 census records that he was a farmer from the German village of Blankenstein in the Hessen region.
