Used as a bedroom for the Morse children, this bedroom was enlarged into a suite in 1852 with the addition of a dressing room and closet to the south, over the half-octagonal library below.

During the Youngs’ ownership, this room was used by Innis Young, Mr. and Mrs. Young’s only son. Innis used this room full-time until he left for boarding school at the Milton Academy, and then Harvard University from 1910 until 1914.
