In 1861 the Harris School on Adams Street at the corner of Victory Road (formerly Mill Street) was erected and named in honor of the Rev. Thaddeus Mason Harris who was the pastor of the First Parish for many years. The property was sold to the Boston Housing Authority (in the 1970s?) for the construction of apartment buildings. At times the school was called the school on the Lower Road.
