"But we already know Neville isn't a Squib and he's already got 
power.  He's
not that bad of a student and always had courage.  He didn't have a 
lot of
confidence, but that grew in the DA.  He's fought in two major 
battles
against Death Eaters."

Except that JKR does not say that it is a squib that gets power as 
an adult.  That is what been assumed but not what she actually 
said.  This is the actual question and the answer.

Will there be, or have there been, any "late blooming" students in 
the school who come into their magic potential as adults, rather 
than as children? By the way, I loved meeting you, and hearing you 
speak, when you came to Anderson's in Naperville. I can hardly wait 
until you tour again. 

Ahhh! I loved the event at Anderson's. It was one of my favorites. 
That is completely true. No, is the answer. In my books, magic 
almost always shows itself in a person before age 11; however, there 
is a character who does manage in desperate circumstances to do 
magic quite late in life, but that is very rare in the world I am 
writing about
