Malfoys on the Tapestry

[Chelle]

No: HPFGUIDX 95764

Sirius says most of the pure-blooded families are related in Book 5.
The Weasleys are related but have been removed, one would think,
centuries ago because of their complete absence from the tapestry
where others are merely burned off. That was a viable reason for their
complete absence, but what of the Malfoys?
The only reference to the Malfoys is Lucius marrying Narcissa and
joining the line through the birth of Draco.
Are the Malfoys so elite they have intermarried within themselves for
centuries, or are they not as pureblooded as one might think?
