Christian Gedde and his family arrived from Lübeck at the port of Oranienbaum on 4 July 1766 aboard the English frigate Love & Unity under the command of Skipper Thomas Fairfax.
They settled in the Volga German colony of Boisroux on 7 June 1767 and are recorded there on the 1767 census in Household No. 42.
In 1769, Christian Gedde moved from Boisroux to Hummel.
The Oranienbaum passenger list records that Christian Gedde was a farmer while the 1767 census records that he was a soldier (Soldat) from Zerbst. The 1767 census records that Christian Gedde came from the German village of Rieben in the region of Dessau.
