The Dinsmore Homestead Foundation The Dinsmore Homestead Foundation purchased the home in 1988 and operates it today. Nearly all the accumulated contents of the home and outbuildings still survive. A collection of nearly 90,000 pages of family documents, including letters, journals and business records, are on microfilm. The Dinsmore Homestead Foundation plans to expand the scope of the site to offer research facilities on early Ohio River Valley culture. Other plans include developing the site as a working pioneer farm.
