Dey Family History
In 1641 Dirck Janszen Siecken Dey, a soldier for the Dutch West India Company, was the first of his family to settle in the colonies. His grandson Dirck Dey, a Dutch born planter, purchased 600 acres of land in Preakness Valley, now present day Wayne Township. The exact start date of construction on the Dey Mansion is unknown, but Dirck Dey started building it in the 1740s. By 1764 Dirck passed the mansion onto his son Theunis. Theunis along with his wife, Hester Schuyler, raised ten children in the mansion. Theunis was a political figure who served on the state council by representing Bergen County and was a member of the charter trustee at Queens college, now present day Rutgers University. He also served as a Colonel in the Bergen County Militia during the American Revolution. It was during his service in the militia that he came into contact with George Washington. This led to Theunis to offer his mansion to serve as Washington's headquarters.
Washington's Preakness Valley Headquarters
George Washington stayed at the Dey Mansion during the American Revolution as one of his Headquarters. This area of the Preakness Valley was chosen because its location, as well as its abundance of food and forage in the surrounding area. On two separate occasions the Dey Mansion served as Headquarters for Washington, once from July 1 through July 28, 1780 and again from October 8 through November 27, 1780.
During his stay Washington and his advisers which included Alexander Hamilton, Robert H. Harrison, Tench Tilghman, David Humphreys and James McHenry used the four rooms on the eastern side of the mansion for their bedrooms as well as their military war rooms. Washington also had numerous visitors while at the Dey Mansion, those of which include the Marquis de Lafayette, General Anthony Wayne, Major General Lord Stirling, Benedict Arnold, General William Howe and the Marquis de Chastellux.
Washington's letters and correspondences during his time at the Dey Mansion totaled 964, for over 1800 written pages. One of which informed him on July 14, 1780 that the French allied support had landed at Newport, Rhode Island. Washington left on July 28 to join them.
During Washington's time away from the Dey Mansion Major, General Benedict Arnold's treason became evident and his accomplice Major John Andre was hanged in Tappan, New York on October 2. Fearing that the British commander Sir Henry Clinton would seek revenge, Washington moved his army once again to the Preakness Valley's Dey Mansion, and arrived on October 8, 1780. He stayed there until November 27, 1780 when he moved his headquarters and a portion of his army to Morristown, New Jersey.
