Reddit reviews Ancient Mysteries of Britain

The Wrekin has stories where it was made by a giant and I've read version of it which mentions devil instead. likely from this book. which I think features other devil/giant stories. this article mentions devil version existing link there another one I can think of but cannot find the name of the place or island it refers to.

this article talks of devil and giant stories and some overlaps link. pretty sure I read some of them via this book

folklore society article talks about eddic/local giants and mentions them being referred to swamped for the devil in some tales link

though boggarts, red man, puck I think can also be called the devil in some stories. so its not always giants
