The Town of Neversink came into formal existence by an act of the Ulster County Legislature dated March 16, 1798. It’s first supervisor, Henry Reynolds, was appointed by that same legislature. Prior to that time, early Neversink or “Neversink Country” as it was sometimes known was part of the Town of Rochester, Ulster County. It was 1809 when Neversink became part of the newly created Sullivan County. In 1809 Neversink included part of Denning, Fremont, Callicoon, Liberty, Fallsburg and all of Rockland townships. In a short period of time, other legislative acts changed property lines and the present boundaries of the Town of Neversink were established.
Historical research is often made difficult because the Town of Neversink moved from one county to another and the boundaries kept changing. Official records may be found in Ulster County until 1814. Only then do records show up in Sullivan County.
