Moreover, Narcissa's sister is a brunette. Do genetics allow for full
siblings to have black and blond hair?

Sherrie here:

Yes. <g>  I'm one of five siblings - growing up (before we discovered the 
wonders of hair dye!), my youngest sister and I were blondes, my brother light 
brown, one other sister a dark true brown, and the last a VERY dark 
reddish-brown.  (We also have eye color ranging the entire spectrum from blue to dark 
brown.)

The mechanics of recessives and incomplete dominants can make for some 
interesting families...
