Somewhat the premise of Alice Bell's excellent books. She's the former Rock Paper Shotgun editor that got binned when the site was bought out and the new owners decided to fire all their most talented writers. The money I've saved when I cancelled my subscription is more than enough to buy her novels.
Also, where are the old, old, old ghosts in bearskins?
There just where less people around then.
So what you are saying is statistically we would be more likely to get a pre-modern era child ghost?
