Usually wrong.
I wasn't aware of the sister, although he may have mentioned her in his work. It just never registered on me. I always got the impression that his older relatives -- parents, grand parents -- didn't take his poetry seriously. He came from a wealthy family and was something of the black sheep of the family. I'm sure his drug addiction didn't help his relationship with them, either. I don't have the sense that any of them, the older relatives, would care about seeing his work continue to be published. Maybe I'm wrong about that. A caring sister might take an interest, however. Just speculating here.
