You must be kidding.Does anyone remember the beloved James Herriot? I love his stories. Only, they're memoirs, not stories. I forget what his real name was, but he kept a list of real names that he cross-referenced with his fictional stand-in names, and changed not only names but places as well, and -- gosh, I don't want to google this -- any way, about the time he was really popular here in the states, it was the mid nineties, and there were James' Herriot Christmas gift books and related paraphernalia at the bookstores at the mall and the BBC was airing a charming series based on his life and stories. Except, when he died -- again, google it to find out the facts -- the whole real town of real people found out it was them he was writing about and decided to sue his estate. (The lawsuit might have been in the late eighties, but it didn't stop the stories from taking on a life of their own as a tv show.)
I think the long of the short of this is, don't just keep an eye out for liable & legal matters, but check to make sure you're not profiting too much from other people's real-experiences. They might want in on it someday.
He was very well-known in the U.K. There was a TV series based on his stories. The notion that there was a whole village of people who didn't know until he died they were being portrayed in stories is just not credible.
