Gross-Umstadt. Wilhelm Adam von Curti was declared bankrupt in 1790. His estate at that time included feudal leases ("lehen") in six towns: Groß-Karben, Klein-Karben, Kaichen, Kloppenheim, Burggräfenrode and Dortelweil, Kurpfalz. The baronetcy became extinct in 1823 with the death of Wilhelm Adam, the last male descendant.
