Kaspar Christian Hildebrandt, a farmer, his wife Anna Margaretha Elisabeth, and children (Hannah Maria Elisabeth, age 7; Johann Heinrich Anton, age 5; Hannah Elisabeth age 2) immigrated to Denmark (Schleswig-Holstein) arriving in Flensburg on 22 May 1762.
They are last recorded in the Danish colonies on 24 April 1765.
They joined the migration to Russia and settled in the Volga German colony of Reinwald on 14 July 1766. They are recorded there on the 1767 census in Household No. 42 along with his sister-in-law Anna Margaretha Seidel.
The 1767 census records that Kaspar Christian Hildebrandt came from England. The Eichhorns record that Kaspar Christian Hildebrandt was originally from the German region of Hannover, but most recently came from the region of Brandenburg.
