Friedrich and Barbara Hahn had two children, both baptized in Hattersheim: Adam (baptized 23 October 1763) and Apollonia (baptized 7 February 1765). Evidently neither of the children survived, as Friedrich & Barbara are recorded arriving in the port at Oranienbaum on 18 Jun 1766 without them.
Friedrich and Barbara are recorded on the 1767 census of Keller in Household No. 18. They do not appear to have had descendants who survived to the 1798 Census.
