Crabbe and Goyle ??

Hello,
   I'm pretty sure I'm just imagining things but it occurred to me 
recently that there seems to be something strange around the 
characters of Crabbe and Goyle.  It was after finishing GoF for the 
second time that the Deatheater scene made me think something was up. 
As Voldy is walking around recognizing his minions, he passes two 
people he refers to as Crabbe and Goyle.  The first time I read this, 
I just assumed they were each a parent of Draco's pals.  I guess what 
got me wondering the second time is that Voldy greets them as Crabbe 
and Goyle rather than the Crabbe's and the Goyle's.  Is it reasonable 
that only one parent would follow Voldy and not the other?  Maybe so 
as it appeared that Lucius' wife wasn't there either.  Anyway, I 
thought what if this Crabbe and Goyle were the same as the ones 
attending Hogwarts!  I know, this is a little far-fetched but at the 
time I also realized that I didn't know either of their first names.  
I have since discovered them at the Encyclopaedia Potterica but still 
have not found them in the books.  I imagine the names are there 
somewhere but it still got me thinking could these two be something 
other than they appear.  Well, I know it's pretty hair-brained but I 
haven't been able to get it out of my head.  Any thoughts?
