Taghkanick, the name of a town in Columbia County and primarily of a tract of land included in the Livingston Patent and located "behind _Potkoke,_" is written _Tachkanick_ in the Indian deed of 1685; _Tachhanick_ in the Indian deed of 1687-8; "Land called _Tachhanick_ which the owners reserved to plant upon when they sold him _Tachhanick,_ with the land called Quissichkook;" _Tachkanick,_ "having the kill on one side and the hill on the other"; _Tahkanick_ (Surveyor's notation) 1715--is positively located by the surveyor on the east side of the kill called by the Indians _Saukhenak,_ and by the purchasers Roelof Jansen's Kill. Of the meaning of the name Dr. E. B. O'Callaghan wrote: "_Tachanûk,_ 'Wood place,' literally, 'the woods,' from _Takone,_ 'forest,' and _ûk,_ 'place'"; which Dr. Trumbull regarded as "the least objectionable" of any of the interpretations that had fallen under his notice, and to which he added: "Literally, 'wild lands,' 'forest.'" It would seem to be more probable that _Tachk, Taghk, Tachh, Tahk,_ etc., represents _Tak_ (Taghk), with formative _an, Taghkan,_ meaning "wood;" and _ek,_ animate plural added, "Woods," "trees," "forest." Dr. O'Callaghan's _ûk_ (ook), "Land or place," is not in any of the orthographies. The deed-sentence, "When they sold him Tachanick," reads literally, from the name, "When they sold him the woods." The name was extended to the reserved field, to the stream and to the mountain. [FN] The latter is familiar to geologists in what is known as the Taconic rocks. Translations of the name from Del. _Tuphanné,_ "Cold stream," and _Tankkanné,_ "Little river," are without merit, although _Tankhanné_ would describe the branch of Roelof Jansen's Kill on which the plantation was located. * * * * * [FN] The purchasers claimed but the Indians denied having sold the mountain. It was heavily wooded no doubt. Livingston claimed it from having bought "the woods." The Moravian missionaries wrote, in 1744, _W'takantschan,_ which Dr. Trumbull converted to _Ket-takone-wadchu,_ "Great woody mountain." Wichquapakat, Wichquapuchat, Wickquapubon, the latter by the surveyor, given as the name of the southeast boundmark of the Livingston Patent and therein described as "the south end of the hills," of which Ahashawagh-kameck was the north. _Wichqua_ is surely an equivalent of _Wequa_ (_Wehqua,_ Eliot), "As far as; ending at; the end or extreme, point." [FN] Now the southwest corner on the Massachusetts line. * * * * * [FN] Robert Livingston, who wrote most of the Indian names in his patent, was a Scotchman. He learned to "talk Dutch" in Rotterdam, and picked up an acquaintance with the Indian tongues at Fort Orange (Albany). Some of his orthographies are singular combinations.
