During the recent Picture Book Idea Month hosted by Tara Lazar, I had a question that popped up (and was referred your way). I have a nonfiction biography I’m working on (creative nonfiction). If the person still has possible living descendants, do you track them down for permission to write about the historical person (if they’re not someone famous)? What would a publisher’s or editor’s perspective be on a project like this? Any idea?
