Leonhard Merckert, his wife, and his son by a previous marriage (Adam Friedrich, age 17) arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard a pink under the command of Lieutenant Moisey Davydov.
They settled in the Volga German colony of Krasnoyar on 20 July 1767 and are recorded there on the 1767 census in Household No. 13.
The Oranienbaum passenger list records that Leonhard Merckert was a physician while the 1767 census records that he was a farmer. Both documents record that he came from the German region of Ansbach.
