Hans Georg Ulrich was born about 1698 in the area of Baden-Durlach in what today is the German state of Baden-Württemberg. He married Maria Rosina, a widow who had been born in 1713. Maria Rosing had a daughter from her previous marriage, Katharina Scheelen, who had been born in 1738. Hans Georg & Maria Rosina had a boy, Hans Georg Martin Ulrich, born on 20 November 1752 in Hagsfeld, today a northeast suburb of Karlsruhe.
Hans Georg and his family immigrated to Denmark (Schleswig-Holstein), departing from Altona, Duchy of Holstein, on 5 May 1761 under the leadership of Andreas Kirchhof. They arrived in the city of Schleswig, Duchy of Schleswig, on 9 May 1761. While living in Denmark, stepdaughter Katharina married Georg Gottlieb Lerch, who had been born in 1743; they had a boy who was named Christian and immigrated to the Volga German colony of Schäfer after July 1763.
