Stighcook, a tract of land so called, now in Greene County, granted to Casparus Brunk and others in 1743, is located in patent as lying "to the westward of Koghsacky." In Indian deed to Edward Collins, in 1734, the description reads, "Westerly by the high woods known and called by the Indian name Sticktakook." Apparently from Mass. _Mishuntugkook,_ "At a place of much wood." The district seems to have been famed for nut trees. It is noted on Van der Donck's map "Noten Hoeck," from which it was extended to Great Nutten Hook Island and Little Nutten Hook Island, on which there were nut trees. (See Wieskottine, Kiskatom, etc.)
Siesk-assin, a boundmark of the Coeymans Patent, is described as a point on the west side of the Hudson, "opposite the middle of the island called _Sapanakock_ and by the Dutch called Barrent's Island." The suffix _-assin,_ probably stands for _Assin,_ "Stone," but the prefix is unintelligible. _Sapanak-ock_ means, "Place of wild potatoes," or bulbous roots. (See Passapenoc.) Barrent's is from Barrent Coeymans, the founder of the village of Coeymans. The earlier Dutch name was Beerin Island, or "She-bear's Island," usually read Bear's Island.
Achquetuck is given as the name of the flat at Coeyman's Hollow. The suffix _-tuck_ probably stands for "A tidal river or estuary," and _Achque_ means "On this side," or before. The reference seems to have been to land before or on this side of the estuary, or the side toward the speaker.
Oniskethau, quoted as the name of Coeymans' Creek, is said to have been the name of a Sunk-squa, or sachem's wife. Authority not given. The stream descends in two falls at Coeymans' Village, covering seventy-five feet. The same name is met in _Onisquathaw,_ now _Niskata,_ of record as the name of a place in the town of New Scotland, Albany County.
Hahnakrois, or Haanakrois, the name of a small stream sometimes called Coeymans' Creek, which enters the Hudson in the northeast corner of Greene County, is Dutch corrupted. The original was _Haan-Kraait,_ meaning "Cock-crowing" Kill, perhaps from the sound of the waterfall.
Sankagag, otherwise written _Sanckhagag,_ is given, in deed to Van Rensselaer, 1630, as the name of a tract of land described as "Situated on the west side of the North River, stretching in length from a little above Beeren Island along the river upward to Smack's Island, and in width two days' journey inland." Beeren Island is about twelve miles south of Albany, and Smack's Island is near or at that city. The western limit of the tract included the Helderberg [FN] hills.
