And again

This was inspired by Brian's comment on my last one. I'm just a puzzling machine. Please let me know, again, if you find more than one unique solution or a contradiction in my clues. Edit: Some minor corrections have been made based on comments.

This is the tale of six brothers: Arnold, Barry, Chester, David, Edward, and Frank. None of them are twins, and each of them has a whole-number age. What are the brothers' ages?

1. Frank is two years older than Barry.
2. Edward is half Chester's age.
3. David is two-thirds Arnold's age.
4. Half of the brothers can legally drink in the US.
5. None of the brothers has reached retirement age.
6. Two of the brothers' ages are prime numbers. Frank's age isn't one of them.
7. David was born between Edward and Barry.
8. Chester is the oldest, Arnold is second-oldest.
9. Barry is six years older than Edward.

Trickier.

Chester is 26
Arnold is 24
Frank is 21
Barry is 19
David is 16
Edward is 13

I will playtest for you anytime. :)

Also, you should probably say something like, "what are the brothers' ages?"

And, if you want to get nit-picky (like, if you're publishing them somewhere), clue #3 should read, "David is two-thirds Arnold's age."
