Quick Facts

 * This was an enormous county, including the northern part of New York State as well as all of the present State of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766 by the creation of Cumberland County, and further on March 16, 1770 by the creation of Gloucester County, both containing territory now in Vermont. - Wikipedia
 * The original owners of this land were men of Massachusetts and Connecticut, Nathan Gorham and Oliver Phelps.
 * They were trustees for thirteen Dutch investors in Amsterdam. Trustees were needed because aliens were not then permitted to own land. This tract was later known as The Holland Purchase.
 * The legal transactions and recordings were conducted in Massachusetts by the General Court assembled and passed in that House of Representatives and Senate. It was approved by John Hancock, the governor of Massachusetts, before it was recorded in New York. Many transactions thereafter recorded include the grantors Nathan Gorham of Massachusetts and Oliver Phelps of Connecticut. A deed in 1817 from Oliver Phelps daughter, Mary, granted land to the school commissioner of Connecticut.
