Matthias Ingenthron, a baker, his wife Anna Maria (who is not the mother of his sons), and his sons (Johann Nikolaus, age 19, and Balthasar, age 17) arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard the snow-brig Der Merkur under the command of Skipper Johann Heinrich Abelmann.
Matthias died after arrival in Russia, and Anna Maria remarried to a man named Weigand. She and stepson Balthasar Ingenthron settled in the Volga German colony of Rothammel on 21 August 1767. They are recorded there on the 1767 census in Household No. 10 with a note that they relocated in 1768 to the neighboring colony of Sewald.
Nikolaus settled in the Volga German colony of Sewald on 20 August 1767 and is recorded there on the 1767 census in Household No. 5 living with the Johannes Dithion family.
In 1822, Jakob Ingenthron moved from Sewald to Kamenka.
The 1767 census records that the Ingenthrons came from the German village of Dirmstein in the region of Worms.
