The derivation of the word Neversink remains uncertain. Present research says the word Neversink came from the Indian name Mahackamack. Earlier historians failed to agree on this and many other possibilities exist.

Historical research is also complicated by the taking of the land by eminent domain for two New York City reservoirs. The Neversink Reservoir is totally in the Town of Neversink, and the two communities of Neversink and Bittersweet were lost at that time. The village of Neversink relocated to its present site along Route 55. The Rondout Reservoir waters covers three lost communities. Town of Neversink lost Eureka and part of Montela. The other section of Montela and the community of Lackawack were located in the Town of Wawarsing, Ulster County.
