Caspar Wilhelm Tucksberg, son of Philipp Tucksberg, was baptized 24 April 1739 in the Evangelical Reformed church in Schwelm. On 31 October 1762 in the Evangelical Lutheran Church in Schwelm, he married Anna Margaretha Rosendahl, daughter of Peter Johannes Rosendahl of Blombacher Bach (Beeck). She was baptized in the Evangelical Lutheran Church in Lüttringhausen on 8 March 1739. Before emigrating to the Volga, Caspar Wilhelm and Anna Margaretha lived in Blombacher Beeck and Marscheid and had two children, both baptized in Lüttringhausen: Maria Gertrud, baptized 23 January 1763; and Maria Catharina, baptized 1 July 1764 (died 23 February 1766).
A list of colonists arriving in Russia on 15 July 1766 includes Caspar Wilhelm Duksberg, his wife Anna Margaretha Rosenthal, and their children Maria Gerdruth, age 3, and Johann Caspar, age 2 weeks.
Caspar Duxberg and his wife Anna are reported on the Transport Lists with a notation that Anna died during the journey to the colonies. Their children are not reported on this list, suggesting that the children died prior to the colonists' departure from St. Petersburg.
Caspar Wilhelm Duxberg and his new wife Elisabeth settled in Boregard. They are reported there on the 1767 Census (First Settlers List) on the list of Temporary Colonists in Household #56.
By 1798, family members and descendants had relocated to four other colonies.
