"The Ea.st Neck " extended from the Mamaroneck river on the east to a small stream called " Pipin's brook " on the west, which divided it from the " Middle ' or "Great " Neck, and is the same which now crosses the Boston road through the land, and just east of the house of the late Mr. George Vanderburg. ' The Middle Neck extended from the latter stream westward to a much larger brook called " Cedar or Gravelly brook " which is the one that now bounds the land belonging to Mr. Meyer ^ on the west.

The " West Neck " extended from the latter to another small brook still further to the westward, termed " Stoney or Gravelly Brook " which was the east line of the Manor of Peiham.

Of the three in their order. The East Neck from Mamaroneck River to Pipin's Brook, upon which Richbell took up his permanent residence about 1665, as near as can now be ascertained, was called by the Indians " Mamaranock Neck." This fact is so stated in the Petition of Richbell of the 24th of December 1661, for a "ground brief" or Dutch license to purchase Indian lands.* A misunderstanding by Mr. Robert Bolton of the word " Mammaranock " in the crabbed writing of this ancient Document as recorded led him to state in the first edition of his History of Westchester County, published in 1848, that the " aboriginal name " of the East Neck was " Wanmainuck,"^ and the error has appeared in the second edition, * and it has been hence followed by other writers. It was a pure mistake in deciphering the written word. The true " aboriginal name of the East Neck was " Mamaranock " the same as the town and village bears to-day under the later spelling of " Mamaroneck." That portion of it between the HarboUr on the east and Pipin's brook and the salt creek into which it runs on the west, bears the name of " De Lancey's Neck " from the fact that it has been possessed as a whole for more than a century and until a few yearsago, and in part still is possessed, by the family of Gov.
