Konrad Leiser, a farmer, his wife Katharina, and children (Anna, age 9; Elisabeth, age 7; Johann [Jost], age 4) 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 Ernestinendorf on 3 August 1767 and are recorded there on the 1767 census in Household No. 37.
Johann Heinrich Leiser, a farmer, and his wife Anna are recorded on the 1767 census of Ernestinendorf in Household No. 38, but they do not appear to have arrived in Oranienbaum aboard the same ship.
In 1769, Conrad Leiser & Johann Heinrich Leiser and his family moved from Ernestinendorf to Schaffhausen.
The 1767 census records that both Konrad Leiser and Johann Heinrich Leiser came from the German village of Atzenhain in the Darmstadt region.
