West Windsor's Territorial Predecessors

West Windsor formed in 1797. So, what was here before? In the preceding centuries, a few distinct, increasingly-small territories encompassed the area. Read on to learn more.

Lenapehoking

The first humans to settle the West Windsor area, the ancestors of the Indigenous "Lenape," migrated to the East Coast around 10,000 BCE, at the end of the last Ice Age. They had gradually crossed the continent from its Pacific coast, and the Atlantic coast was their last frontier.[1] 

Their territory, the "Lenapehoking," stretched from eastern Maryland up to western Connecticut. It included all of present-day New Jersey and portions of New York, Pennsylvania, and Maryland (see Map #1).[2]

The Lenape were not one unified tribe; rather, within the Lenapehoking were numerous autonomous tribes, each with their own unique cultures and histories.[3] Those in the West Windsor area were called the "Assunpinks" - a name meaning a "rocky, watery place."[4] Their most obvious legacy here is the Assunpink Creek, running through southern West Windsor.

The Lenape did not have property lines as we see them today, nor did they recognize individual land ownership. Rather, they maintained general tribal territories cooperatively. Thus, the Lenapehoking, West Windsor's earliest territorial "predecessor," was not a well-defined legal entity - rather, it was a general region in which the Lenape lived. However, of course, this is no longer the case. Over time, European pressures drove most (but not all) of the Lenape out of their longtime homeland and changed the territory forever. The Lenape likely left the West Windsor area by the early 1700s (if not earlier) and most migrated west out of New Jersey more broadly by the early 1800s.[5] To learn more about this mass migration and the Lenape in general, click here.

New Netherland and New Jersey

In 1524, amid an era in which several European countries were staking claims to immense swaths of North America, Giovanni de Verrazano became the first European to explore the land now (2025) commonly called New Jersey.[6] However, it was not until the early 1600s that Europeans permanently settled in the Lenapehoking.

​In the 1610s, Dutch settlers established trading outposts in New York. and the next decade (1624) they permanently settle "New Netherland" as a Dutch colony. Its territorial claims stretched from Massachusetts down to Delaware, including most of modern New Jersey.[7] However, there is no evidence that any colonist ever actually settled in the West Windsor area during New Netherland's existence.

In 1664, England annexed the colony in a bloodless takeover. On August 27 of that year, English frigates sailed into the harbor of New Amsterdam (New Netherland's capital, centered on present-day southern Manhattan). In the face of overwhelming power, the colony's director-general, Peter Stuyvesant, surrendered and New Netherland was now under English control.[8]

Two months prior, James, Duke of York, had granted Lord John Berkeley and Sir George Carteret ownership of all land between the Delaware and Hudson Rivers. The charter formally named the territory “New Jersey,” in honor of Carteret's defense of the English Channel island of Jersey during the English Civil War. It also set the stage for a regional surge in colonial acquisition and settlement.[9]

A Tale of Two Jerseys

Within the next few decades, thousands of Europeans arrived in New Jersey, seeking wealth and freedom.[10] During this time, a group of wealthy land-owners called the "Proprietors" collaboratively governed the colony. Notable figures like William Penn - famed Quaker and founder of Pennsylvania - were granted millions of acres of land to settle or sell.[11]

In 1676, a document called the "Quinpartite Deed" split New Jersey into two halves: "East Jersey" and "West Jersey."[12] Each half had its own constitution and governors, and distinct cultures. West Jersey, adjacent to Pennsylvania, had a larger concentration of Quaker settlers and landowners (including William Penn), whereas East Jersey was generally more secular.[13],[14]

Almost immediately after the division, disputes arose as to exactly where the division line was between the two Jerseys. The first attempt at a resolution was the "Keith Line" (AKA the "Provinice Line"), surveyed by George Keith in 1687.[15] It was soon partly altered by the "Coxe-Barclay" Line to form the official boundary (see adjacent map).[16] Two other lines - the Thorton Line of 1696[17] and Lawrence Line of 1743[18] - were also proposed, but both had virtually no relevance to the future West Windsor region. 

The area that would eventually become West Windsor sat within East Jersey but also at the West Jersey border, along the Keith Line/Province Line. Today, large portions of both Quakerbridge Road and Province Line Road follow the old Keith Line.[19] This location yielded a mixture of colonial religions - Quaker, Presbyterian, Baptist, and more - as well as nationalities - most notably English and Dutch.[20] Even after East and West Jersey forever reunited into a whole New Jersey in 1702,[21] these influences persisted for generations.

Counties, Towns, & Local Acquisition

As New Jersey became increasingly colonized through the late 1600s, the need to establish counties and townships grew apparent. In 1683, the General Assembly of East Jersey, located at “Elizebeth-Town” (Elizabeth) formed the counties of Bergen, Essex, Middlesex, and Monmouth.[22] It was Middlesex County that contained all of present-day West Windsor until Mercer County's formation in 1838.[23] On October 31, 1693, Middlesex County further divided into Woodbridge, Perth Amboy, and Piscataway townships.[24] Piscataway thereafter included land south of the Raritan River – including all of present-day West Windsor.[25]

The 1690s also marked the start of individual land acquisition in the present-day West Windsor area. The earliest known purchase was by William Watson in or before 1690.[26] By the year 1700, several others had bought immense swaths of land as well. The largest tracts, of several thousand acres each, were owned by William Penn[27] and an English goldsmith named David Lyell.[28] Collectively, they owned the vast majority of the land that would later become West Windsor.[29],[30],[31] The old division line between their two gargantuan estates was, in the 1860s, formally surveyed as a farm lane and named "Penn-Lyle Road."[32],[33],[34]

Most of these 1690s-era landowning families (including the Penns and Lyells) likely never set foot in the future West Windsor area, let alone settle here. However, a few of them did in the 1690s - notably the Groomes,[35] Bainbridges,[36] and possibly the Tindalls.[37] Despite this, colonial settlement was sparse for the next few decades. In fact, it was not until the 1730s that the future West Windsor area began to see its first large wave of colonial settlement.

Windsor Township

In 1723/4, New Brunswick Township was formed,[38] and in December 1730, the City of New Brunswick was chartered. This stripped all land south of the Raritan River from Piscataway Township. However, the 1730 charter failed to account for the territory south of the Millstone River, leaving much of Middlesex County an ungoverned orphan.[39]

An entirely new municipality, called "Windsor," arose in this political vacuum.[40] It was presumably named after the royal town of Windsor, England and formally incorporated in 1751 as a township. It spanned all of present-day West Windsor, East Windsor, Robbinsville, and Hightstown; all of Princeton southeast of Nassau and Stockton Streets; and slivers of Millstone and Monroe Townships (see adjacent map). However, of course, in the mid-1700s, none of those municipalities existed; instead, there was only Windsor Township.[41]

The 1730s marked a period of rapid settlement. Numerous families, predominantly Dutch and English, were drawn to the region's fertile soil and waterways. They transformed the previously forested and meadowed land into vast swaths of farmland, stretching to the horizon in every direction. They built houses, mills, churches, burial grounds, barns, and other structures. Some of these still exist, and a handful belong to West Windsor's "100 Club." They also built dirt farm lanes to connect early villages like Hightstown and Princeton, as well s smaller hamlets such as Clarksville, Dutch Neck, Edinburg, Grovers Mill, and Penns Neck. For generations thereafter, agriculture dominated the area's identity, only succumbing to suburban and commercial developments in the mid-late 20th century.

A Tale of Two Windsors

However, by the 1790s, a conflict had formed between the western and eastern halves of the town over the maintenance of roads—then dusty, rutted lanes that needed frequent upkeep and depleted municipal coffers. Also at the time, Windsor Township residents often identified with Princeton in the northwest and Hightstown in the southeast, depending on which one was closer to them. Whatever the reason, a movement grew to split the township. Within a few years, Windsor was no more. ​By an act of state legislature finalized on February 9, 1797, Windsor split into two halves – East Windsor and West Windsor.[42] West Windsor Township held its first formal meeting on April 8, 1797.[43] To learn more, click here.

For the next several decades, West Windsor retained all of Princeton up to Nassau Street – including the Princeton Battlefield, Nassau Hall, the Stony Brook Meeting House, and many other historic sites. Even though Princeton Borough was created in 1813,[44] it wouldn't become a fully-independent municipality for many more years.[45]

Middlesex County retained West Windsor until Mercer County’s formation on February 22, 1838.[46] Five days later, a supplementary act annexed a 0.7-acre tract from West Windsor, including the Princeton University campus, to Princeton Township (see adjacent map).[47] And a final land transfer in 1853 similarly ceded the rest of all remaining land, west of the Delaware and Raritan Canal, from West Windsor to Princeton.[48]

​West Windsor’s borders have remained virtually unchanged ever since.
