In 1661, Philipp Erwein, Baron von Schönborn (1607–1668), of Freienfels Castle near Weinbach, since 1654 also owner of Geisenheim, the only brother of Elector-Archbishop Johann Philipp von Schönborn, purchased the Herrschaft (territory) of Heusenstamm and built a new castle.
DDG Hansa gave many of its ships names ending in -fels ("rock"), (e.g. D/S Freienfels, D/S Uhenfels, D/S Wachtfels), so that collectively they became known as the "Fels ships".
