Hi, I am not related to this family but I do cemetery research in upper Westchester County. I worked on the clean-up on the Heady cemetery by the Boy Scouts several years ago. I have a listing of who is buried in the cemetery and also have the will of Thomas Hadden and an article on the Heady family of New Castle by Michele Rose (from the New Castle Historical Societys newsletter dated 1993). My ancestors (Orser) lived on the adjoining property of John McCord. Norman MacDonald wrote a book (about 60 pages) on the McCord Farm at Ossining, NY 1750-1937. It is available from the Ossining Historical Society.
