Question: Katie Bell’s age and the next quidditch captain

No: HPFGUIDX 87604

Does anybody know canon for Katie Bell being two years older than 
Harry?

The reason I ask is that I have assumed one of the interesting 
questions for Book 6 is whether Harry or Ron will be the Gryffindor 
quidditch captain (BTW my bet is on Ron). But reading OotP again I 
came across p. 575 (US addition), where Jinny says she wants to be a 
chaser. She mentions that Angelina and Alicia are both leaving next 
year, but she does *not* mention Katie. Now, if Katie is only a year 
older than Harry, she has the best chance to be the captain, as the 
oldest member in the team.

The HP lexicon puts Katie in the same year with Angelina and Alicia, 
but I couldn't find on what canon this is based. It is true that she 
always hangs with them but this is not conclusive evidence. Maybe it 
is only female chaser comradeship.

In addition, we know that Harry was the only first-year player for 
100 years. This means that if the year of SS/PS was not Katie's first 
season in the team, then she must be two years older than Harry, but 
I could not find canon for this either (Lee Jordan says in SS/PS that 
Alicia was only a reserve last year, but Katie's past experience is 
not mentioned).

Now I'm not saying I lose sleep at night thinking neither Harry nor 
Ron will be the captain in Book 6, but PLEEEEASE HELP ANYBODY!!!!
