I must agree with both Christopher and Debbie.  It's also very likely 
that the Weasleys only wanted Bill and Charlie.  And Percy was an 
accident.  Since there's such a large gap (9-10 years) between the 
children, they decided to have another so Percy wouldn't be alone.  
But, they got the twins: They have eachother.  They then had Ron but 
by then, Percy was already three years old.  Too old some might 
think.  Since the twins had eachother, they had another and got 
Ginny.  Thus, Bill and Charlie have eachother.  Ron and Ginny have 
eachother and the twins have eachother.  And Percy has no one (poor 
Percy) and that contributes to his character develepement.
