Help in debunking old poltergeist cases

I am looking for skeptical sources or information in debunking some old poltergeist cases. They are:

Battersea poltergeist
Slawensik poltergeist
Staus poltergeist
Stratford poltergeist

If anyone has any information then please put it in this thread. I will continue to update this thread with my findings.
