 The like-named brook crops up in records from the years 1585 to 1588, likewise with the name Pielsbach.Writers Dolch and Greule trace the name back to a pre-Germanic waterway name, "Pelisa", to which the placename ending "—bach" was added in German/Germanic times.It is understandable that within the limits of what once was Ulmet's comparatively vast municipal area, villages stood in earlier times that have now vanished.
