The Wilton Historical Society Neighborhoods and Old Houses Collection contains draft survey forms, index photographs, research notes, and other documentation relating (for houses) to date of construction, ownership history, major renovations, and relocations, and (for neighborhoods) dates of settlement, the names of founding and notable residents, prevailing economic activities and local businesses, the origins of local names, and the history of local roads. The information available for individual houses and neighborhoods varies widely. The earliest items date to the 1730s, but the bulk of the collection is mid- to late twentieth century.
