JKR defines "Squib" as the nonmagical child of *magical* parents, so 
the child of two Squibs would *not* be a Squib because his or her 
parents would not be magical. In other words, that child would be a 
Muggle, the nonmagical child of nonmagical parents. If that's the 
case, "a long line of pureblood Squibs" is a contradiction in 
terms....>>>

The Sergeant Majorette says

I differentiate between what JKR tells interviewers and what she puts 
in the heads and mouths of her characters. I think we're meant to 
see, from the reader's perspective, that these distinctions are 
meaningless, like the difference between quadroon, octoroon and 
mulatto, or the kind of thing we read about years ago in South Africa 
where a child in a family was arbitrarily reclassified racially and 
had to be registered as a live-in servant in order to remain in the 
family home.

When you get right down to it, a long line of pureblood *anythings* 
is a contradiction in terms. No "pure" line lasts very long: the 
consequences of inbreeding cuts them short. As our Ron says (in the 
book; in the movie, Hagrid has the line) wizards have to intermarry 
with Muggles or they'd die out.
