Numerous proprietors operated the mill during its more than 300 year history. Many of them made changes and improvements to the business. The earliest portions of the current structure were built by Earl Simons about 1862. Charles F. Lewis added a shed with a sawmill in the 1880s. His son Charles T. Lewis replaced the waterwheel with an electric motor to grind the various flours. Subsequent owners sold seeds, fertilizer, and poultry supplies. The Larsen family took over in the 1960s and operated the business as a general purpose hardware store. The mill pond is gone, but remnants of the first mill apparatus can be seen inside the building. Copyright 2015 Windsor Historical Society.
