The Third Floor is where the fabulous ballroom was located. We know that in 1915, Sherman Fairchild hosted a reception for West Point Cadet Augustus M. Gurney and used the ballroom. Other Oneontans also had fond memories of many parties here.
There were rooms adjacent to the ballroom for the servants and a stairway leading from the third floor on the Grand Street side, down to the second floor in addition to the stairway in the rear. Renovations by the Masonic Lodge have sealed this stairway off and also removed much of the servants' quarters.
