Denning, NY

Town of Denning, located in Ulster County NY, is comprised of three distinct areas. The valley of the West Branch of the Neversink River, now referred to as Frost Valley and Round Pond areas. The East Branch of the Neversink River known as the Denning Valley included the hamlets of Denning, Ladleton, Red Hill, and Dewittville. The Sundown Area included hamlets of Sundown, Peekamoose, Bull Run, Dymond City, Greenville, and Yeagerville.

These areas were part of a tract given by the English Queen Anne to one Johannes Hardenberg in 1708. The Hardenberg Patent was surveyed in 1749 and divided into lots. Denning covers parts of great lots 6 and 7 which were further divided into lots which were sold to investors and called tracts. William Denning eventually purchased 19,169 acres when a Philadelphia land grant corporation failed to pay taxes. After Denning’s death William H. Denning purchased some 24,000 acres which were again surveyed and divided into lots and sold.
