I have an idea for a middle-grade narrative nonfiction and wanted to know what kind of legalities are involved with using the person's name in the book. This would be a narrative account based on the events that unfolded about 50 years ago that gave this person their 15 minutes of fame. This is not a famous person, just someone who did something pretty monumental as a child that made headlines at the time. So I would cast this person as the narrator and re-tell the story as a creative or narrative nonfiction -- a work of fiction based on actual events with some scenes recreated or even added in order to tell the story. It would be targeted toward middle grade, so something between 20-30k words and not too deep on all the details -- mostly just the bones of the story written for elementary age readers with the information from the story coming from credible sourses. If I were to make it an adult book, I would certainly track the person down and conduct my own interviews in order to get more in depth. But this would just be a "surface" story for readers in the 7-12 ballpark. The facts collected for the story would all come from credible sources -- mostly newspaper articles from the time as well as a couple interviews the person gave to the media later in life (this person is still alive) that recounted the story. I would include a "notes" section at the end to cite my sources for various recreations, etc. (My background is in journalism so I'm quite familiar with this aspect). So what would I be up against? Do I need permission to use the person's name given the understanding that this is a work of fiction? If so, what kind of process does that involve? Also, hypothetically, what if the person were no longer alive? Lastly, would using a fictional name of the person change anything as far as being able to attribute the book to that person's story? (Basically saying that the book is based on their experiences but all names have been changed) Thanks very much for any words of wisdom.
