Karen:
I have just been rereading OOP and this struck me.
"I haven't looked at this for years.  There's Phineas Nigellus... my 
great-great-grandfather, see? Least popular headmaster Hogwarts ever 
had...and Araminta Meliflua...cousin of my mother's...tried to force 
through a Ministry Bill to make Muggle-hunting legal..."  
Pg 113 of the US version.

This says to me that the House of Black comes from Sirius's mom or 
she did indeed marry into her own family for her cousin to be on the 
family tree.

Carol:
Thanks for catching that, Karen. Clearly Mrs. Black *is* talking about
her own ancestry (as well as her husband's since it's "the House of
Black"), but I don't think we need to have her marrying her own first
cousin to explain it. More likely we just have both sides of Sirius's
family represented in the tapestry.

The fact that Phineas is Sirius's great-great-grandfather but has a
different last name does indicate that he's not Sirius's father's
father's grandfather, but there are seven other possibilities, four on
Sirius's mother's side and three on his father's (everyone has eight
great-great-grandfathers). Phineas's presence suggests to me that even
though the tapestry was identified as "The Noble and Most Ancient
House of Black," it shows the ancestors (and close living relatives)
of both Mr. and Mrs. Black, which would explain Mrs. Black's
possessiveness and references to "her" family without necessitating
her marrying a cousin with the same last name. (Narcissa and Bellatrix
would be cousins on the father's side, according to my theory, but
still part of Mrs. Black's "family" as pureblood relatives of her
husband. Phineas, OTOH, could well be her own ancestor, but is still
part of the "House of Black" through his connection to her.)

Having not only Phineas but a definite maternal relative, Araminta
Melliflua, on the tapestry pretty much destroys my theory that the
Potter and Snape families don't show up because they're on Sirius's
mother's side of the family, but it's still possible that the Potter
or Snape connections were so far back that their presence on the
tapestry they would require some diligent searching to discover
(assuming that the names had not been removed). It would be rather
time-consuming and laborious to search for ancestors from more than a
few generations back, simply because the tapestry must have been so
huge and so crowded. It's quite possible that Sirius, who was not
obsessed with blood relationships, never made the effort to explore it
thoroughly and consequently was unaware of his exact relationship to
the Potter and Snape families, or he could have chosen not to mention
the connection(s) to Harry.

Carol, who still thinks that the three families must be related
because of the small number of pure blood families
