126 North Champlain Street is a one and one-half-story, two bay, gable-front, wood frame dwelling on the west side of North Champlain Street between Peru and North Streets. Like 40 and 48 North Champlain Street, it has few stylistic embellishments, and the hood above the entrance door and bay window on the west elevation are later additions. A rear addition was constructed between 1919 and 1926.1
This structure was probably built between 1853 and 1857.2 From 1866 to 1870 it was occupied by J. Hickey, a laborer.3 Dennis O'Dea bought the property in 1871, and lived there until 1920, when he sold it to Patrick J. Henry.4 Henry, a retiree, owned the building until 1944, sometimes taking on boarders like Mrs. Sarah L. Morrison, a widow.5
