Wilhelm Geist married Anna Catharina Schoch on 11 April 1761 in Leimen. A note in the parish register indicates that they are going to Jutland [Denmark].
Wilhelm Geist, a farmer, and his wife Anna Katharina immigrated to Denmark (Schleswig-Holstein) arriving in the city of Schleswig on 30 May 1761. They pledged their oath to King Friedrich of Denmark on 24 July 1761 and eventually settled in the Danish colony of Königsbach. They were dismissed from Denmark on 17 May 1763, and joined the migration to Russia.
They settled in the Volga German colony of Balzer on 26 April 1766. They are recorded there on the 1767 census in Household No. 17.
The 1767 census records that Wilhelm Geist came from the German region of Kurpfalz.
There are no known surviving male lines of this Geist family among the Volga German colonies.
