Anne Squires:

This is from "The Leaky Cauldron and Mugglenet interview Joanne
Kathleen Rowling: Part Three," The Leaky Cauldron, 16 July 2005 with
Melissa Anelli and Emerson Spartz.


MA: What about Harry's family — his grandparents — were they killed?

JKR: No. This takes us into more mundane territory. As a writer, it
was more interesting, plot-wise, if Harry was completely alone. So I
rather ruthlessly disposed of his entire family apart from Aunt
Petunia. I mean, James and Lily are massively important to the plot,
of course, but the grandparents? No. And, because I do like my
backstory: Petunia and Lily's parents, normal Muggle death. James's
parents were elderly, were getting on a little when he was born, which
explains the only child, very pampered,
had-him-late-in-life-so-he's-an-extra-treasure, as often happens, I
think. They were old in wizarding terms, and they died. They succumbed
to a wizarding illness. That's as far as it goes. There's nothing
serious or sinister about those deaths. I just needed them out of the
way so I killed them.

MA: That sort of shuts down Heir of Gryffindor [theories], as well.

JKR: [Pause.] Yeah. Well - yeah.


Anne again:

So, Harry is not the Heir of Gryffindor.
