Open research question
Trace the earliest surviving documentary source for the discovery of the Hexham Heads and for each major associated paranormal claim, including object movement, poltergeist activity, animal-like apparitions, witness accounts, and experiences reported by Anne Ross.
A source, research note, or further-reading link closes this question when staff accept it. Evidence and corrections stay attached for staff and do not close it by themselves.
Staff review every contribution before it is added to the file. A correction is a proposal: accepting it does not replace the official record. Rejected items are handled like rejected case submissions.
