Johann Melchior Hahn (born 7 October 1713) married on 17 November 1740 to Anna Elisabeth Göbel (born 16 February 1715). They have 5 known children, all baptized in the Lutheran Church in Oppenrod, a very small village just east of Giessen: (1) Johann Philipp, baptized 30 September 1742; (2) Thilmann, baptized 18 February 1744; (3) Johann Jacob, baptized 8 May 1746; (4) Anna Elisabeth, baptized 14 January 1748; and (5) Johann Melchior, baptized 12 October 1749. All of the children except for Johann Jacob immigrated to Russia, departing from the port in Lübeck.
They arrived on 8 August 1766 in Oranienbaum aboard the galliot Anna Catharina which had Johann Joachim Janson as skipper. The brothers Thilmann & Melchior arrived in the Volga German colony of Paulskaya on 3 August 1767 and spent the winter there. It is unknown what happened to either the older brother or their sister.
In 1796, widow Katharina Justina Hahn and her children moved from Hockerberg to Urbach.
Descendants of the Thilmann Hahn family can be found in Hockerberg and Urbach while the Melchior Hahn family is residing in Basel by 1798 (Household No. Bs44).
