Ron's Wand

As I'm fairly new here I'm not sure if this is a topic you've covered 
here before, but it suddenly occured to me that, according to the 
"rules" Ms. Rowling has set up about the world of wizards, Ron should 
not have been able to inherit his wand from one of his older siblings 
(from which one, I'm not sure as I haven't got the book here in front 
of me). When Harry was buying his wand at Ollivander's, Mr.
Ollivander 
himself told him that "the wand chooses the wizard," and not the
other 
way around. How, then, was Ron able to manage with that old hand-me-
down wand of his? (I suppose one could argue that Ron WASN'T in fact 
able to use it properly, and that this might be the cause of some of 
the "mishaps" that he experienced in his first several years at 
Hogwarts, such as the belching-up-slugs incident, but I'm not sure I 
agree with that.)

Another theory I considered for a short time was that since Ron is a 
blood relative of whomever he inherited the wand from, that's why he 
could get it to work. Has anyone got any other ideas?

Sincerely,
Ella :)
