Jefferson County History

The section of New York State now comprising the county of Jefferson was a formidable frontier wilderness without permanent settlement either by Native American or European settlers until after the Revolutionary War. Ownership was claimed by the Oneida Indian nation because of exposure to frequent raids from hostile tribes across the St. Lawrence River, not even the Oneida tarried very long in the region while on occasional hunting or trapping expeditions.
