Battle of Oriskany relic - $100

Hi from San Francisco! My dad and I are family history nerds.
Our farthest-back US ancestors fought in the battle of Oriskany.
We've looked for relics from this battle, but have been able to find anything.
We've only ever found items from the USS Oriskany or from the NY State Park memorializing the battle.
That's not quite what we're looking for! We're more looking for items from the Revolution in Oriskany - either area or battle itself.
If you have something you'd be willing to part with, please reach out.
It would mean a lot to our family history project! Thanks so much for reading this far.
