Ancrop, or Ankerop as otherwise written, was a sachem of the Esopus Indians in 1677, and was still serving in that office in 1722. He was obviously an old man at the latter date. He had, however, no jurisdiction over or part in the sale of the lands to the New Paltz Company in 1677. His testimony, given forty-five years after the sale by the Indians, was simply confirmatory in general terms of a location which had been made in 1677, and the interpretation of what he said was obviously given by the Justices in terms to correspond with what his employers wished him to say. In the days of the locations of boundmarks of patents, his testimony would have been regarded with suspicion. Locations of boundmarks were then frequently changed by patentees who desired to increase their holdings, by "Taking some Indians in a public manner to show such places as they might name to them," wrote Sir William Johnson, for many years Superintendent of Indian Affairs, adding that it was "Well known" that an Indian "Would shew any place by any name you please to give him, for a small blanket or a bottle of rum." Presumably Ankerop received either "A small blanket or a bottle of rum" for his services, but it is not to be inferred that the location of the boundmarks in 1677 was tainted by the "sharp practice" which prevailed later. It is reasonable to presume, however, that the name would never have been removed from the foot of the hill had not the Groot Stuk been situated as it was with reference to a southeast line drawn from its apex to Juffrouw's Hook.
