GalleyCat had an item on a New York Times staffer who wrote some columns about her family's secrets. She grew up knowing her father had a dark past, but it wasn't until her mother was dying that she found out how dark it was—like something out of the Sopranos. The articles were NYT Select, which means you have to pay to read them online, but I found similar reports elsewhere.
Once the articles came out, the writer was approached by folks offering her a book deal if she wrote her memoirs, which is why GalleyCat picked it up. They're even talking movie options.
I have to say, I don't see it as an ideal path to publication. She suffered growing up, and she suffered even more once she found out the whole truth. I'll take obscurity and a happy childhood, thank you very much.
