There's no canon designation of full-blood; only pure-blood, half-
blood, and muggle-born (and Muggle, of course).  Some people say that 
Harry's and Ginny's kids would be pure-blood but I don't see how 
because Harry remains a half-blood.  Some fans confuse magical status 
with blood status, which isn't the same at all.  If two Muggle-borns 
marry, their children aren't going to be pure-blood even though both 
parents are magical.
