His grandson Dirck Dey, a Dutch born planter, purchased 600 acres of land in Preakness Valley, now Wayne Township. 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 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 in 1780.
