Thomas Samuel Swartwout

Thomas "Maas" Swartwout (c. 1660 – c. 1723) was one of the earliest settlers of the Neversink and Delaware River Valley, early landowner in colonial America, one of seven holders of the Wagheckemeck (Minisink Region) Peenpack land patent then in Ulster County October 14, 1697 and one of seven founders with Pierre Guimard, Jacques Caudebec, Anthony & Bernardus Swartwout, David Jamison and Jan Tyse of pre1798 Deerpark, Orange County, New York.

[1][2] He married Elizabeth Jacobse Jansen Gardenier on February 4, 1683 in New York, British Province.

The same indefinite knowledge regarding the position of the boundary line between Orange and Ulster counties existed.

The first boundary line separating the two counties extended across the territory of the present town of Deerpark not far south of the village of Huguenot to a point on "the northwardmost branch" of the Delaware River, near Sparrowbush.

On the death of Swartwout, around the year 1723 in Machackemeck, New York, Samuel, his son, took charge of the family property.
