Got this answer on copyright and trademark law. "I'm a retired lawyer, so this isn't a "legal opinion." I can't charge you because my law license is "inactive." Titles of books and names of fictional characters normally can't be copyrighted. So, don't worry about this. If you want to make and sell dolls with Jeannie's name, beware of trademark issues." Not in my plans!
For those curious, no, I don't plan to make this the start of a series. This was a one-off type of piece that I started a decade ago and decided to finish off. Nor do I intend to write stories based on any of the story ideas listed in either Future Plots or Memo - Reply. Those ideas were simply part of the story within the story. Thanks for the interest.
