Christoph Eberhard, son of Georg Eberhard, was born in 1712 in Spöck, north of Karlsruhe. [In 1975, Spöck voluntarily merged with Blankenloch, Büchig, Friedrichstal, and Stafford to found the administrative village of Stutensee.] Christoph married Anna Margaretha Metz, daughter of Adam Metz, on 4 June 1732 in the Blankenloch Lutheran Church.
They had nine children, each baptized in Blankenloch: (1) Johann Georg (baptized 14 August 1732); (2) Anna Margaretha (baptized 20 November 1735); (3) Johann Christoph (3 January 1737); (4) Jakob Martin (baptized 23 July 1739); (5) Maria Katharina (baptized 6 May 1742); (6) Johann Adam (baptized 11 March 1745); (7) Christina (baptized 24 June 1748); and (8 & 9) twins, Anna Maria & Johann Friedrich (baptized 25 July 1752).
Christoph, his wife, and six of their children immigrated to Denmark (Schleswig-Holstein), departing from Altona, Duchy of Holstein, on 29 June 1761 under the leadership of Johann Thomas Gabler. Before 1761, son Johann Georg had married to Magdalena (born 1731) and they brought along their maid Barbara Huber. Also son Johann Christoph had married to Christina (born 1743). The extended Eberhard family arrived in the city of Schleswig, Duchy of Schleswig, on 4 July 1761. There, son Jakob Martin married Margaretha (born 1734), and Johann Adam married Eva Katharina Metz (born 1740).
Christoph's sons Johann Georg & Johann Adam lived in Denmark until January 1765, when they immigrated to Russia. They settled in the Volga German colony of Grimm where they are recorded on the 1775 Census in Households No. 46 (Adam & family) and No. 47 (Georg & family).
In 1788, Johann Adam's widow married Just Jung and moved to the colony of Schwab along with two children.
Descendants of these Eberhard immigrant families are identified on the 1798 Census in Schwab (Household No. Sb21) & Grimm (Households No. Gm027 & Gm059).
