Johannes and his wife (Helena Lutzer according to the baptism of the oldest child) had two children according to Danish parish records: Maria Magdalena, baptized 16 July 1760, and Johann Peter, baptized 15 July 1762, both in Karup Parish, Viborg Amt. Andreas and his wife also had two children: Maria Magdalena, baptized 6 Jun 1761, and Anna Margaretha, baptized 9 January 1763, both in Friderichsheede, Karup Parish, Viborg Amt. The two families left Denmark on 26 April 1763 and joined the migration to the Russian Volga.

They are recorded there on the 1767 Census of Anton in Households No. 31 (Johannes) and No. 34 (Andreas). Their descendants are recorded in Anton on the 1798 Census in Households No. An45 - An47.
