"apple, mulberry, chestnut, and hazel nut"
that's a great start. Are you thinking humans + livestock or just livestock?
I would add:
American Persimmon (Diospyros virginiana) - Depending upon varieties, mulberry can take you June - August, and Apple/Persimmon can take you July-March (unharvested fruit of many varieties will hang through frost and drop throughout the winter)
Cornelian Cherry (Cornus mas)
Hickory/oaks that makes sense for your area
Asian pears (great disease resistance)
Hawthorne (for nutraceutical fruit for livestock)
a few Black Walnuts (as a browsable parasiticide)
Black locust (as browsable forage + postwood)
