Maddy:

What I think is likely to be the most interesting part of the tapestry
is what is *not* on there. I'm very skeptical that the Blacks were
actually toujours pur. In one generation there were at least two
(Sirius and Andromeda), so I can't help but think there are more burn
marks on it.

I think there might be some canon evidence to support the idea that
Snape and Sirius are related. (At least, it could be)

(from Chapter 24, Occlumency, starting on page 457 from
Bloomsbury/Raincoast)

'Sit down, Potter.'
'You know,' said Sirius loudly, leaning back on his rear chair legs
and speaking to the ceiling, 'I think I'd prefer it if you didn't give
orders here, Snape. It's my house, you see.'
An ugly flush suffused Snape's pallid face.

To me it doesn't seem to be enough that it's simply Sirius's house to
cause Snape to blush like that. What if Snape was Sirius's half
brother, and the elder one? (We now know that Snape's birthday is in
January) If he was the elder, illegitimate child, Sirius mentioning
that the house belongs to him could be a slap in the face to Snape if
he could have been the first born son and entitled to any Black
inheritence, such as the house.

Call me crazy, but I think this makes some sense. Any thoughts?
