Johannes Jung Sr., a day laborer (Tagelöhner), and his family immigrated to Denmark (Schleswig-Holstein) in 1763. In 1765, his son Solomon (along with his new wife and her children by the deceased Jakob Meier) joined the migration to Russia.
They settled in the Volga German colony of Holstein on 2 May 1766 and are recorded there on the 1767 census in Household No. 25.
The 1767 census records that Solomon Jung came from the village of Eutin[gen]. The Eichhorn research records that Solomon Jung was the son of Johannes Jung Senior who was from Eutingen in the Markgrafschaft of Baden-Durlach.
