Stacy here again:
OK so I did some digging in the HP Lexicon, which says little re: squib blood status.  The 
lexicon defines Pure Blood as follows:

pure-blood
A witch or wizard of 'pure' wizarding ancestry, without any Muggle ancestors whatsoever 
as far as can be determined.

The Lexicon then goes on to describe a sqib as follows:

A Squib is not a Muggle. Born to a wizarding family, a Squib has such a low level of 
magical power that he or she is essentially unable to do any magic at all. However, while a 
Squib cannot cast spells, he or she can apparently see magical beings such as poltergeists, 
though not dementors (JKR).

So this leads me to believe that if there is a squib in the lineage, it does not change the 
blood status of the descendants, so long as there are no muggles or muggle-borns in the 
family.

And just an aside, in ch.1 of DH, Voldemort mentions something about getting rid of 
everybody else so that only those of the "true blood" remain.  He never says "pure blood" 
because he is a half-blood himself.  He is so much like Hitler here.  

Thanks all for your thoughts on this issue.  The fic I'm going to write will tackle racism and 
prejudice in the wizarding world, and how a death eater is "made".  I will post on the 
HPFGU announcement board when the first chapters will be online, though I don't forsee it 
happening any time soon.  I have a lot of research to do.
