Following on from the information about “Molly the Dreamer” at Gatcombe Lodge:
“Molly is also supposed to have dug at the Longstone, where she did find gold, but lightning flashed just as she was about to lift it out; ‘after that she was never the same again’.”
From an article in ‘Folklore’ (1912), mentioned by Westwood and Simpson in their 2005 ‘Lore of the Land’.
