 As a fief from the Hornbach Monastery with its centre at Glan-Münchweiler, all this area's villages passed first in 1323 to the Raugraves in the Nahegau, and thereafter, in 1344, to the Archbishop of Trier and the Breidenborns in 1388.In connection with the Münchweiler valley, the village of Steinbach and the now vanished village of Frensweiler were both mentioned repeatedly, although the latter was mentioned earlier.A man named Conradus de Vrodenswilre was mentioned as far back as 1313 in the family Mauchenheim's cartulary, while a village named Frinßwiller was named in 1419 in the family Breidenborn's cartulary.
