I didn't know about all the political motivations they had to edit and present the stories in the way they did. It is obvious many of the stories are edited (or are at least slenderised versions) and are not 'as spoken' tales*.

The Victorian beliefs were things I found when I was researching about Alice in Wonderland, but I was doing an essay not a thesis so I grabbed from professional achademic's conclusions. Which then dragged me into UK folklore with all its boggarts and barguests. Many of those tales were recorded by people striving to be accurate historians or academics so I must have just overlaid the later English motivations onto the Grimm brothers work. Wow, I really make sucky assumptions when I'm not bothering to think about things critically.

*I had always put that down to the potential actions of a translator though.
