Johann Kaspar Leitner and his family arrived from Lübeck at the port in Oranienbaum on 12 May 1766 aboard the galliot Anna Catharina with the skipper Daniel Geier at the helm.
They settled in the Volga German colony of Katharinenstadt on 16 January 1767 where they are recorded on the 1767 census in Household No. 4. By this time Johann Kaspar Leitner is married to Anna Dorothea Pracht, believed to be the widow Pastern who is from the German village of Grünberg.
It appears that all the male descendants of this Leitner family moved to the colony of Biberstein where they are recorded on the 1798 Census.
