Dirck (also spelled Direk) Keyser secured a lease to the land from Rutsen on June 17, 1680, and built the first house in Rosendale; the terms of Keyser's lease stipulated that he build a stone house on the property at the base of what is now Joppenbergh Mountain. On June 23, 1682, fifteen members of the Esopus tribe sold Rutsen more land, by the Rondout Creek. This land was surveyed by Philip Wells on May 28, 1685; Wells declared the size of the purchase to be south of the creek, and to the north. There was also a island within the creek. Rutsen was given a patent for the combined area on August 26, 1686.
