Doreen and Steven -Thank you for the advice... I'm not certain we have ID'd 
the
culprits precisely since the damage doesn't really match images I have found
online of either stinkbug, oriental fruit moth, or coddling moth damage.

Since the damage looks at least somewhat similar to the images I have found of
Stinkbug damage, my plan for next year will include the preventative
neem-spraying Doreen suggests.

Thanks again,
Sincerely,
Warren Goodwin

PS: In response to Steven's query: I've got two mature peach trees and three
immature trees.
