In 1343, Hans Truchseß was mentioned in a directory of Wetzhausen. It was written: “Notation regarding Mr. Hansen Truchseß, soul of a knight of Brünnhausen and his wedded wife. Owned Wetzhausen, Brünnhausen, Eßfeld and part of zu Sternberg.” His four Sons inherited these four places after his death and started four independent lines which later branched out even more. Diez, the actual founder of the Wetzhausen line, was given by his father, Hans, all of Wetzhausen and one third of Brennhausen.
