Widow Anna Margaretha Trimper and her daughter Elisabeth (age 23) arrived from Lübeck at the port of Oranienbaum on 22 July 1766 aboard the pink Lev under the command of Lieutenant Fyodor Fyodorov. [Their names are believed to be recorded in reverse on the passenger list.]
They settled in the Volga German colony of Grimm. The mother Anna Margaretha is recorded there on the 1767 census in Household No. 16 along with her daughter Anna Katharina and son-in-law Johann Heinrich Aab. The daughter Elisabeth married Valentin Reich and is recorded on the 1767 census of Grimm in Household No. 11.
The 1775 census of Grimm records them respectively in Households No. 103 and 93.
The Oranienbaum passenger list records that the Trimper family came from the German region of Darmstadt.
There are no known surviving male descendants with the Trimper surname among the Volga German colonies.
