Anton Hassler and his wife Sophia arrived from Lübeck at the port of Oranienbaum on 15 September 1766 aboard the galliot Adler under the command of Skipper Paul Adam Drath.
Anton Hasler and his wife Sophia are recorded on the list of colonists being transported from St. Petersburg to Saratov in 1767.
They settled in the Volga German colony of Seelmann on 5 September 1767 and are recorded there on the 1767 census in Household No. 47.
The Oranienbaum passenger list records that Anton Hassler was a farmer from Hungary while the 1767 census records that he was a carpenter (Tischler) from Linz in Austria.
There are no known surviving male lines of this family among the Volga German colonies.
