Jakob Busch, a farmer, immigrated to Denmark (Schleswig-Holstein) arriving in Flensburg on 29 May 1762 along with his son Philipp (age 13). Jakob married there to Christina Bauer, daughter of Melchior Bauer. Jakob Busch and his family 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 Balzer on 28 March 1766. They are recorded there on the 1767 census in Household No. 19 along with Anna Susanna Bauer (age 30). Althought the 1767 census does not record a relationship between the Busch and Bauer families, the records in Denmark record that Christina Bauer and Anna Susanna Bauer are sisters.
In 1792, Jakob Busch moved from Balzer to Lauwe.
The 1767 census records that Jakob Busch came from the German region of Kurpfalz. The Eichhorns record that Jakob Busch came from the German village of Käferthal near Mannheim in the Kurpfalz region.
