Both the Prussian census of 1772 and the diary of Aeltester Gerhard Wiebe refer to Baumgart, Prussia, as the residence for Elias Peters. Son, Daniel Peters, and Elisabeth Brandt had only one child, according to records – Daniel Daniel Peters (1794 – 1879). He came to Russia in 1806 with his maternal grand-parents, Jakob J. and Susanna Brandt, although this fact is contradicted in some documents.
