66 George Street is a two-story, two by five bay, gable-front, asymmetrical, wood frame building on the east side of George Street between Monroe and Peru Streets. An ell was added to the rear of the building by 1890,¹ and half of the porch on the south elevation was enclosed by 1900.² After 1942, the large dormer above the porch was constructed and the rear half of the porch was enclosed.³

The structure was built between 1857 and 1869,⁴ probably for Robert Hunter, a blacksmith.⁵ Fred Isham, an employee of the National Biscuit Company, lived in the house from 1895 until at least 1904.⁶ In 1907, the Michaud estate purchased the property and held it until 1963. The Michaud family themselves lived in the house until at least 1940, counting in their number cabinet makers and a bookkeeper.
