Hywel ap Evan

I revisited Benjamin’s house and asked him what he thought might be behind these strange disappearances. He showed me a photocopy of an article from the Daily Courant. The article was dated 07/08/1759. 

So there was a local poet who worked in the lead mine called Hywel ap Evan. He was sacked from the mine for practicing dark magic. Soon after he and twenty locals all disappeared. The villagers and mine workers were rightly up in arms. Could there possibly be some connection between this and the other cases?

I did a search for Hywel ap Evan’s poetry and found nothing. I guess I’ve got to email some universities.
