It's from Notes and Queries, which (as you might know) is like a Victorian version of an internet forum (honestly) with people casting questions out across the country and people replying if they can. Just took a bit longer in those days. People used to give themselves pseudonyms rather like today too. I can read the archive because I've got a password from my library, otherwise you have to pay up. But I can email you what it says if you like (it's a bit long to bore people with here maybe). It's about the folklore of the Rollrights and the area.
