William Thomas House ("Old Stone House"). 850 South Bluff Boulevard; 1838.The house is the second oldest (some say it is the oldest) structure still standing in Clinton. It is of vernacular construction with modern, recent-day additions, in the 1840's, the Old Stone House was an overnight stopping point for pony mail riders and for other travelers.The one-story stone house, built in 1836-1838, consisted originally of one room with fireplace and a sleeping loft above. Later, another room was added. Stone quarried on the site was used for the walls, and wood materials came from oaks felled nearby. In the 1930's, the house was enlarged and modernized by E. I. Troeger. Expansion consisted of three bedrooms, kitchen, laundry, and partial basement built with stone from a Princeton, Iowa quarry. In 1956, the Peterson family had the kitchen modernized and added a family room, garage, and new entryway of vertical board and batten wood siding.
