Snape and Narcissa

Okay, hopefully this has not been discussed before.  I searched and 
did not find anything, but then, I might not have used the correct 
terms to search with ;-).  I have always wondered why Snape favors 
Draco.  It cannot simply be because Draco is a Slytherin...I suppose 
it could, but I do not think so.  Is there anyway that Snape and 
Narcissa could be related?  Brother and sister? (they are so 
different in appearance, I just don't know about that one)  Cousins? 
I am just wondering if there is some sort of familial tie there that 
makes Snape fond of Draco (if you can call it fond).  Does someone 
have a theory on this?  I know it isn't a big, interesting question, 
but it has me wondering.
