Johann Georg Mützig was born in 1721 near Worms. He married first Anna Margaretha (surname unknown). They had six children, each baptized in the Catholic Church in Rheindürkheim just north of the city of Worms right along the Rhein River: (1) Johann Gottlieb, baptized on 5 July 1748; (2) Matthias, baptized on 28 November 1750; (3) Maria Katharina, baptized on 9 May 1753; (4) Peter Paul, baptized on 16 March 1755; (5) Johann Georg, baptized on 25 March 1757; and (6) Johann Jakob, baptized on 8 September 1759. About 1761, Johann Georg's wife died. He remarried to Anna Margaretha Reissenbaum on 7 March 1762 in Rheindürkheim. They had a daughter who was named Anna Maria, baptized on 30 June 1763; she died before 1766. At the beginning of 1766 they had another daughter, who was named Margaretha.
Johann Georg Mützig and his family immigrated to Russia. They departed from the port of Lübeck aboard the galliot Die Fortuna under the command of the skipper Peter Stahl, and arrived at the port in Oranienbaum on 4 July 1766.
During the transport to the Volga German colonies, the sons Matthias, Johann Jakob, and Peter Paul died. The remaining family members arrived in Göbel on 20 June 1767 where Johann Georg is recorded on the 1767 census in Household No. 56; his son Johann Gottlieb in Household No. 55.
By the time of the 1798 census, sons Johann Georg & Johann Gottlieb are still living in Göbel and are recorded there in Households No. Gb30 and Gb49 respectively.
