The Dudley Form House was built in 1844 by Erastus Dudley for Ruth, himself, and his son Nathan, who was soon to wed Sophonia. Its Greek Revival style matched many houses built during the 1840's, although its interior followed a fairly traditional and conservative plan that shared much with houses a hundred years older. One room stood to the left and right of the chimney, with a keeping room along the rear containing a large cooking fireplace. Around 1880, the house began to change with the addition of a Victorian parlor and side porch, along with changes to the kitchen and dining room. Shortly after 1900, further modernization came with a north addition for the older Nathan and Sophonia. At that time, the large center chimney was removed and replaced with a smaller brick chimney serving the parlor stoves and the new kitchen iron range, and more changes were made north of the kitchen to link the new north addition. A shed behind the house was used to store firewood and do laundry, and beneath it was a large cistern that collected water from the roofs. Nathan and Sophia raised five children in the house, and it later passed to their only son Erastus, who married Martha Munger. With their two children, Mable and Nathan, three generations continued living in the house.
