Student Names mentioned in Sorting Ceremony No.1

OK, I couldn't find any posts about this, so sorry if it's a repeat!

I am re-reading the series wth an eye to names and "random" items.

In PS/SS during the sorting ceremony there are 24 names mentioned. 
Most of them turn up again later in other books; AND they are either 
in the DA or Slytherin. But there are several names not mentioned 
again (and the lexicon has nothing but PS/SS on them either).

Names we have seen again: Hannah Abbott, Susan Bones, Terry Boot, 
Millicent Bulstrode, Lavendar Brown, Justin Finch-Fletchley, Seamus 
Finnigan, Hermione Granger, Neville Longbottom. Draco Malfoy, (Crabbe 
and Goyle), Nott, Patil, Patil, Harry Potter, Dean Thomas, Ron 
Weasley.

Who are THESE? Mandy Brocklehurst(Ravenclaw), Moon, Sally-Anne Perks, 
Lisa Turpin (Ravenclaw).

OK, so we have four students in Harry's year who we have not "seen" 
again. Two of these do not have their house named. Might this Moon be 
the unnamed Syltherin boy in OOTP? Will we see these four in the next 
two books?

Any ideas? Or posts that have discussed this that you can direct me 
to? :-)

Thanks!
