SSSusan:
Of all this juicy stuff put forth, I latch onto this tiny rub.  But 
there you have it.  WHY would this comment of Hermione's be true?  If 
the generational span of yer average witchorwizard is 2 to 3 times that 
of a human, wouldn't it be *easier* to trace the family tree?  At least 
easier back to a set point in comparison to muggles?  You know what I 
mean?  Say you want to go back to 1450 or to 1200 -- there'd ostensibly 
be a lot fewer generations to trace for the witch or wizard than for 
the muggle.

Doesn't matter much in the scheme of things, but....
