Lackawack appears of record as the name of a stream in Sullivan County, otherwise known as the West Branch of Rondout Creek, and also as the name of the valley through which it passes. The valley passes into the town of Wawarsing, Ulster County, where the name is met in the Beekman and in the Lowe patents, with special application to the valley above Honk Falls, and is retained as the name of a modern village. In the Lowe Patent it is written Ragawack, the initials L and R exchanged; in the Hardenberg Patent it is Laughawake. The German missionary orthography is _Lechauwak_ (Zeisb.), "Fork, division, separation," that which forks or divides, or comes together in the form of a fork; literally, "The Fork." _Lechauwak,_ "Fork"; _Lechau-hanne,_ "Fork of a river," from which Lackawanna; _Lechau-wiechen,_ "Fork of a road," from which Lackawaxen--"abbreviated by the Germans to _Lecha,_ and by the English to _Lehigh._" (Reichel.) Napanoch, on the Rondout below Honk Falls, is probably the same word that is met in _Nepeak,_ translated by Dr. Trumbull, "Water-land, or land overflowed by water." At or near Port Jervis, Napeneck, Napenack, etc. The adjectival is _Nepé, Napé,_ "Water." Wassahawassing, in the Lowe Patent and also in the deed to Lowe from Henry Beekman, is probably from _Awossi-newás-ing_ (Del.), "At the point or promontory beyond," or on the other side of a certain place. Mopochock--"A certain Great Kil called Mopochock," in patent to Joachim Staats, 1688, is said to have been the name of what is now known as Sandberg Kill, but was not, as that stream was in no way connected with the Staats Patent. Naversing is entered on Pownal's map between Rosendale and Fountain creeks, in the old town of Rochester. The map location may not be correct. The name is from _Newás-ing,_ (Del.), "At a point or promontory." The familiar form is Neversink. Mattachonts, a modern orthography, preserves the name of a place in the town of Rochester, Ulster County, and not that of an Indian maiden as locally stated. The boundary description refers to a creek and to a swamp. The record orthographies are Magtigkenighonk and Maghkenighonk, in Calendar of Land Papers, and "Mattekah-onk Kill," local. Amangag-arickan, given as the name of an Indian family in western Ulster (Col. Hist. N. Y., xiii, 505), is probably from _Amangak,_ "Large," with the related meaning of terrible, and _Anakakan,_ "Rushes," or sharp rushes. _Amangak_ is from _Amangi,_ "Big, large, powerful, dire," etc., and _-ak,_ animate plural. Ochmoachk-ing, an unlocated place, is described as "Above the village called Mombackus, extending from the north bound of the land of Anna Beake southerly on both sides of the creek or river to a certain place called Ochmoachking." (Patent to Staats, 1688.)
