Johann Christian Gutherich was born on 21 February 1739 in Gammelsbach, south of Beerfelden (today in Baden-Württemberg). He married in nearby Wald-Michelbach on 9 January 1759 to Anna Katharina Albrecht who was from neighboring Siedelsbrunn.
They evidently immigrated first to Denmark (Schleswig-Holstein) and then on to Russia. The baptisms of two children are recorded in Danish records: Johann Michael, baptized 5 December 1671 in Friderichshaab, Vorbasse Sogn, Ribe Amt, and Eva Catharina, baptized 22 Mar 1763 in Friderichshaab, Randbol Parish, Vejle Amt.
They settled in the colony of Anton on 7 September 1764. Christian is recorded there as a widower along with his daughter Eva Katharina (age 4½) on the 1767 census in Household No. 12.
This surname does not appear to have continued among the German colonies along the Volga River.
