More Harry Potter

The Weasleys are a huge family. There are established interactions: Fred and George are definitely the jokesters; Percy is definitely the uptight academic. It's fairly clear throughout that the twins have potential that they direct towards joking, and few people in the family actually like Percy as a person. Part of me is curious about how the lesser-known Weasleys interact. How does Bill feel about Ginny, since he's the oldest and she's the youngest? Ginny might not have even been around when Bill left for boarding school - how does he view her, as someone who only interacted with his sister on holidays? How often do Charlie and Bill see the rest of the family? What does Charlie think of his sister joining the Quidditch team? How does he feel about Ron being a lousy Keeper in Quidditch? What do they think of Harry and Hermione marrying into the family?

I feel like J.K. Rowling knows all these things, and I would love to know these answers.
