It therefore corresponds to two County Seats.

The former estate home of James Rogers of the J & J Rogers Company is located in the hamlet. James Rogers the 1st and John Weed were half brothers. They had the same father. James was born in October 1804 in Warren County, NY and John Weed was born in May 1813 in Caldwell, New York, known today as Lake George, New York. However, John did not legally have his father's surname of Rogers until 1844 when he became John Weed Rogers. The Rogers were prominent citizens originally from the Saratoga region, and business owners who settled in The Forks before 1830. Being earlier settlers, they established and operated the J & J Rogers Co., then purchased the Palmer Hill Iron Mines; they owned and operated the J&J Rogers Iron Co. consisting of their Rolling Mill Forge, the 4-fire East Forge on Forge Street, and the 6-fire Forge in the hamlet of Lower Jay. They operated the Iron Ore Mines on Palmer Hill, Kilns in Swastikia, their huge Charcoal Kiln at Taylor Pond, Company Stores in Au Sable Forks and in the Black Brook Hamlet. Their Industrial Era businesses consisted of the J & J Rogers Co. Pulp Mill, the Hydro Electric Dam at that 1897 Pulp Mill that was in the County of Essex, in Au Sable Forks. The Robeson Acid Plant and the 1901 Paper Mill were across the Au Sable River in the County of Clinton, but still in Au Sable Forks, NY. They employed numerous people dating backing to the establishing Au Sable Forks, as their businesses thrived. They constructed Company Houses for their employees and their families. In Oct. 1970, the economy of the bustling village nearly disappeared after the closure of the huge Paper Mill. It was the end of that Industrial Era. Many men from there were and remain today employed by NYS Dept. of Law Enforcement as Correctional Officers and some as NYS Troopers.

Au Sable Forks made national headlines in 1987 with the disappearance and subsequent murder of 17-year-old Kari Lynn Nixon, whose story was featured on Unsolved Mysteries.
