William Penn, by warrant of February 17, 1699, directed surveyor Henry Hollingsworth to layout land for his younger children in this new
country. A plan was made of 35,000 acres of which Wi1liam Penn, Jr. received a
patent in May 1706 for 14,500 acres. Approximately 8913 acres of this land
comprised the area we know as New Garden Township, while 5587 acres adjoined us
in Mill Creek Hundred, New Castle County, Delaware. Another parcel, patented to
daughter Letitia, was in the area now known as Kennett Square. Both sections
were named "Manor of Stenning" (or Steyning), probably for Steyning Hundred in Sussex, England.
A picturesque land of forests with clear creeks running
through, rock-topped hills and outcroppings, marshy valleys and wildlife in
abundance, it lies within drainage of two watersheds - the west and southwest
portions drain into the White Clay Creek, while the eastern part drains into
the Red C1ay Creek. Most of the land is moderately sloping and somewhat
rolling, but the southern part is steeper, with slopes breaking sharply into
valleys. The highest point is north of Toughkenamon with an elevation of 483
feet above mean sea level; the low point of 180 feet above mean sea level is
found where Broad Run leaves the Township in its southern boundary. Its geology
consists of (1) Baltimore gneiss; (2) Setters formation; (3) Cockeysville
marble; (4) Wissahickon formation; and (5) Gabbro. The profiles of soils mapped
in the Township are moderately deep and moderately permeable with good water
holding capacity. Its only human inhabitants were probably the Lenni-Lenape
Indians whose territory ran from the Delaware Bay to New York State.
