Is The Conjuring 4: Last Rites Based on a True Story?

Is The Conjuring 4: Last Rites Based on a True Story? To put it briefly, probably not. To put it even more briefly, absolutely positively definitely not. Oh, that was actually way less brief, sorry about that.
Just in time for the newest Conjuring movie, episode 39 of Madame Strangeways is the latest installment in my paranormal deep dives into Ed & Lorraine Warren's case files. This story is the basis for The Conjuring: Last Rites, but you don't need to have seen any of (or care about) the Conjuring movies to listen! The Smurl Family Haunting in 1986, who were allegedly tormented by a demon and three ghosts in their home: an evil demon who wants to destroy them, an evil woman ghost who wants to destroy them, a confused old lady ghost with Alzheimer's, and a ghost man with a mustache.
I start the episode with a retelling of most of the purportedly true activity as published in the purportedly true book The Haunted: One Family's Nightmare, then get directly into the research and breakdown. Classic horror movies, Satanic Panic, The Beach Boys, Harlequin Romance Novels... and the incubus and succubus who prey on the married couple.
