McGonagall's Name on 1971 Plaque

[Kayla <kdoucette@gt.rr.com>]

Hello, everyone!  I was watching HPSS movie the other day with my 
kids, and I noticed something I hadn't noticed before.  It's right 
after Harry finds out he's the new seeker on the Quidditch team.  
It's the scene where Hermione shows Harry his father's Seeker plaque 
in the trophy case.  They zoom in on James Potter's name, and that's 
where I saw it...there's a "1969 R.J.H. King" plaque, then a "Seeker 
James Potter 1970" plaque, then the plaque to the right has "1971 
M.G. McGonagall" on it!  I paused the DVD & zoomed in on it just to 
make sure.  Professor Minerva McGonagall is too old to have her name 
on a 1971 plaque (since she's over 70 yrs. old), SO I wonder if she 
has a son or daughter around the age of James Potter?  Professor 
McGonagall DOES enjoy Quidditch a lot (she's very competitive).  I 
wonder if this is a clue to future books, or if it's a mistake in the 
movie?!  What do you think?
