The Josiah Cowles House is a historic house at 184 Marion Avenue, in the Plantsville section of Southington, Connecticut. It is a 2-1/2 story wood frame structure, five bays wide, with a central chimney and a wide double central door. Although traditionally ascribed a construction date of 1728, the architecture suggests it was built closer to 1750.
The house was the residence of Captain Josiah Cowles, one of the early settlers of Southington. Cowles was born in Farmington, Connecticut on November 20, 1713. He was a justice of the peace and a captain in the local militia. He held a number of town offices, and was viewed as a leading man in town. At the very first town meeting after the incorporation of Southington, held November 11, 1779, the residents appointed Cowles, along with Jonathan Root to a committee to "provide for the families of officers and soldiers in the field.":378 In 1774, Cowles was appointed to a committee to deliver provisions to Boston, in response to the British blockade of Boston harbor.:180
