I know very little about Johann Salomon Löffler other than his father Johann Löffler was from and born in Jessingen (Wurttemberg) Germany. He died in Schafhandler. Johann Salomon Löffler was the brother of Elisabetha Rosina Löffler, my direct ancestor. They both immigrate to the US. Elisabetha Rosina Löffler settled in Ohio. Their mother was Swiss.
This is really all I have, let me know if any of this information shows a connection.
