There's a The Case is Altered in Sutton Coldfield - can anyone explain the origins of the name?

I remember the Old Mother Redcap in north London - maybe Camden or Islington? I used to know the story attached to the name, but can't remember now. Something about a local witch?

What about The Quiet Woman? One pub sign I remember shows the woman in question carrying her decapitated head, and I'm sure I remember hearing a story about another one who was drowned in a well - very sinister.
