Post by HannigaholicPost by Derek DriscollI've seen referances of "unknown Gryffindor girls." What's that all about?
I think it's the fact that we only know the names of 3 gryffindor girls in
Harry's year - Parvati Patel, Lavendar Brown and Hermione Granger
Unless I've missed the others' names - I'm sure it can be worked out using
the notebook (or at least narrowed down) - somebody posted the link for it
but I can't remember it
It arises from the student count developed from one of the books, I think SS
where we know there are 40 new first-year students. With 4 houses, evenly
dividing the students out to 10 new ones per house. Since we know of 5 boys
in Harry's group (himself, Ron, Seamus, Dean and Neville), we can assume
there are 5 girls, of which only three are known (Hermione, Lavendar,
Parvati).
Also, of the number of Gryffindors during the Boggart study in PoA (where
Neville confronts Snape-dressed-as-grandma), the Boggart goes through 9
transformations: 1 for Lupin (the silver orb), and 8 for the students.
Hermione and Harry do not confront the Boggart, so if each other student got
one chance at it (I've already counted Neville's two confrontations as one
because the Boggart re-assumed the Snape doppleganger at the end) that means
10 Gryffindor students.
This is explained better on the Harry Potter Lexicon site.
