Pam, I did a little checking in the county history books I have and found no listing for Cornwall in the following: 1. Landmarks of Orleans County 2. Pioneer History of Orleans County, NY 3. Orleans County History 1976 4. Pioneers of Massachusetts However, on the Orleans County, NY genweb, there is a will listed for Ozias, Clarendon, 1831. The reference # is 15-988, code a. You may be able to request a copy to be sent to you via the Orleans Co. Clerk's Office @ 585-589-5334. Good luck with your search. Carolyn
