... You've seen the movie Desert Hearts, right? You know it was based on a novel that was based on the author, Jane Rule's, actual life? You aren't by any chance actually related to her or anything like that? ("Jane Rule" was, I believe, a pseudonym.)

Wow, what a cool story. If there are any family documents regarding their lives together, it would be a really good idea to get them to the state historical society or to the University of Arizona's library. The U. of A. has a terrific women's studies/gender studies department - you might try contacting their department chair to see about this.
