Forgive me of my Barbara Bancroft kick. But the woman is rather fascinating.
Barbara Bancroft was revered as a heroine of Grayson, being called the Mother of Grayson, while she was called the Harlot of Satan by the Faithful. They made Bancroft the living example of their Doctrine of the Second Fall. Some on Grayson even compared her to the Lady of the Lake, a mythological figure. (HH2)
I always thought the Lady of the Lake was just myth as well, with no chance of truth. Then I stumble upon this. The old adage, there's always a little truth in legend?...
Claimed locations of the Lake: Wikipedia
