At the end of Charlotte's Web, three of Charlotte's daughters decide to stay in the barn with Wilbur. E. B. White names them Joy, Aranea, and Nellie. Their names are mentioned three times, always in that order.
I seem to be the only person on the internet (or anywhere else, including The Annotated Charlotte's Web) to posit the theory that White chose those names because their initials spell JAN, in honor of his niece Janice Hart White. As a child, she inspired her uncle to start writing children's books. In Letters of E. B. White, there are three letters that White wrote to his niece, all of which begin "Dear Jan".
