Mount Misery (EN) / Pedn Grelynn (KW)
Where the Mount Misery roundabout now stands, was a field called Pedden Grawling 1766; Pedengrawling 1780. A framed 18th century estate map in Trereife House shows exactly where this was (not named as such on the Tithe maps); and it was where the roundabout now is!
