10 April 1606
King James I chartered two Virginia Companies, headquartered in different English cities, to establish colonies along the coast of North America, including islands within 100 miles and, by implication, extending inland 100 miles. Both charters covered New Jersey. The Virginia Company of London was assigned the coast between 34 degrees and 41 degrees north latitude, and the Virginia Company of Plymouth was assigned the coast between 38 degrees and 45 degrees north latitude. The colonies of the two companies were to be at least 100 miles apart, even where the grants overlapped. (Paullin, pl. 42; Swindler, 10:1723; Van Zandt, 92)
1613
The Dutch established trading posts on the Hudson River and claimed jurisdiction between the Connecticut and Delaware rivers, including present New Jersey. (Van Zandt, 74)
1624
The Dutch established the first European settlement in the area of New Jersey at Fort Nassau (now Gloucester, N.J.) and erected the colony of New Netherland to cover an area that included New Jersey and part of New York. (Snyder, 4)
12 March 1663/1664
King Charles II granted to his brother, the Duke of York, an enormous territory that included New Jersey and colonies to the north and east. The Dutch actually controlled the areas of New York and New Jersey. (McCormick, 16; Pomfret, Colonial New Jersey, 56; Swindler, 7:161163)
24 June 1664
New Jersey was created when the Duke of York sold the area (not yet occupied by the English) to John Berkeley and George Carteret for a proprietary colony. The area was defined as all land between the Delaware and Hudson rivers and south of a straight line from the intersection of the Delaware River and the parallel of 41 degrees north latitude to the place where the parallel of 40 degrees north latitude crossed the Hudson River. Actual transfer was August 1665. The straight line between the rivers ran through an area unsettled by colonists and was not demarcated. (McCormick, 17; Swindler, 6:375377; Van Zandt, 79)
29 August 1664
From August to October 1664 the Duke of York's forces fought the Dutch, captured New Amsterdam (29 August 1664), took control of New Jersey, and renamed the province New York. The Treaty of Breda (1667) confirmed this conquest. The governor of New York administered New Jersey. (Parry, 10:231; Pomfret, Colonial New Jersey, 5)
July 1673
In the summer of 1673 Dutch forces recaptured New Netherland, including the area of present New Jersey. (Parry, 13:136; Pomfret, Colonial New Jersey, 31; Swindler, 4:282)
9 February 1673/1674
The Treaty of Westminster ended the Anglo-Dutch war and restored the Dutch and English colonies to their pre-war affiliations. The English proprietors of New Jersey regained actual control by the end of November 1674. (Parry, 13:136; Pomfret, Colonial New Jersey, 31; Swindler, 4:282)
29 June 1674
King Charles II re-granted to the Duke of York the territory he had granted on 12 March 1663/1664, including New Jersey. (Snyder, 89; Swindler, 6:387389)
29 July 1674
The Duke of York confirmed his sale of the northern half of New Jersey to George Carteret but did not address the title of investors who had bought John Berkeley's claim to the rest of the territory. (Pomfret, Colonial New Jersey, 36; Snyder, 8; Swindler, 6:387389)
13 November 1675
Four county-style courts were created in New Jersey; each was known by the towns it covered: Bergen and vicinity; Elizabeth and Newark; Woodbridge and Piscataqua; and Middletown and Shrewsbury [not mapped]. (Leaming and Spicer, 96; Snyder, 12)
1 July 1676
George Carteret and the other New Jersey proprietors executed the Quintipartite Deed to divide New Jersey into two distinct colonies, East New Jersey and West New Jersey. Both colonies were unorganized and technically were non-county area, and here they are known, respectively, as Non-County Area (West) and Non-County Area (East). A version of the dividing line that was different from the original specifications was accepted and demarcated in part in 1687 (Keith Line), the remainder was redefined in detail in 1688; segments of this line have been used to compose many county boundaries. Parts of the 1688 line must be estimated, and this compilation uses the versions chosen by John P. Snyder for his book on New Jersey's internal boundaries. Another survey of the dividing line, more accurately reflecting the original deed, was performed in 1743 (Lawrence's Line); it affected land ownership but not the county lines. (Snyder, 9, 13; Swindler, 6:398; Van Zandt, 79)
1681
West New Jersey created from the Non-County Area (West) the county-like courts of Burlington and Salem but did not provide definite limits for them [not mapped]. Together, the unbounded courts covered the southern half of the colony, which area is mapped here as a single polygon under the name Indefinite Counties Area. The northern portion of the colony remained completely unorganized. The boundary between Non-County Area (West) and the Indefinite Counties Area is estimated to run along Assunpink Creek, where the line between Burlington and the non-county area would be formalized in 1694. (Snyder, 12)
7 March 1682/1683
BERGEN, ESSEX, MIDDLESEX, and MONMOUTH were created as the four original counties in East New Jersey. They covered the entire colony; Non-County Area (East) eliminated. Two segments of the line between ESSEX and Non-County Area (West) must be estimated, and this compilation uses the versions chosen by John P. Snyder for his book on New Jerseys internal boundaries. (Shaw, 1:212, 231; Snyder, 1011, 2931; Wall and Pickersgill, 1:63)
1685
West New Jersey created the county-like court of Cape May from Burlington at the southern end of the Indefinite Counties Area; limits of Cape May also were not defined completely and clearly [not mapped]. (Snyder, 12)
26 May 1686
West New Jersey created the county-like court of Gloucester between Burlington and Salem courts within the Indefinite Counties Area; limits of Gloucester also were not defined completely and clearly [not mapped]. (Snyder, 12)
8 January 1686/1687
Commissioners from East and West New Jersey settled details of the boundary to separate their colonies. Their version of the boundary lay to the west of the line described in the Quintipartite Deed of 1676. In April and May of 1687, George Keith surveyed the new line from Little Egg Harbor to the South Branch of the Raritan River where he was stopped. Segments of that boundary, known as the Keith Line, have been the basis for many county boundaries. (Another survey of the dividing line, more accurately reflecting the original deed of 1676, was performed in 1743. That became known as Lawrence's Line, and it affected land ownership but not county lines.) As a result of that change, ESSEX gained from Non-County Area (West), MIDDLESEX gained from Non-County Area (West) and from Burlington Court in Indefinite Counties Area, and MONMOUTH gained from Burlington Court in Indefinite Counties Area [Burlington not mapped]. (Snyder, 9, 31)
14 May 1688
SOMERSET was created in East New Jersey from MIDDLESEX; not fully organized, attached to MIDDLESEX. (Leaming and Spicer, 305; Snyder, 12, 29)
15 August 1688
The Dominion of New England formally incorporated East New Jersey (15 August 1688) and West New Jersey (18 August 1688) in accordance with the new royal governor's second commission (7 April 1688) and instructions (16 April 1688) from King James II. No change in counties. (Docs. of N.Y., 3:537, 554; Pomfret, Colonial New Jersey, 6566)
5 September 1688
The Non-County Area of West New Jersey gained from ESSEX and SOMERSET in East New Jersey when the absentee governors of East and West New Jersey agreed on a compromise boundary between the two colonies from the north end of the Keith Line (1687) eastward to New York. This line was the boundary between the colonies until 1702 when they were unified, after which it continued as a boundary between counties. Two segments of the boundary between ESSEX and Non-County Area (West) must be estimated, and this compilation has adopted the versions chosen by John P. Snyder for his book on New Jerseys internal boundaries. The southern limit at Assunpink Creek is estimated, based on long use. (Snyder, 9, 31)
18 April 1689
Upon learning of the Glorious Revolution (replacement of King James II by King William III and Queen Mary II) in England, Bostonians imprisoned the royal governor and other officials, thereby ending the Dominion of New England. Over the next months the Jerseys and the other colonies that had been united to form the Dominion had to resume self-government. Local officials in East and West New Jersey continued to perform their duties on their own authority until proprietary government was re-established in 1692. (Craven, 224; Morris and Kelly, pl. 11; Pomfret, Colonial New Jersey, 67)
12 November 1692
CAPE MAY gained from Indefinite Counties Area in West New Jersey after Cape May Court was converted to a county and the boundaries were defined completely and clearly. The division between Burlington and Gloucester courts in West New Jersey was redefined, but remained unmappable [not mapped]. (Leaming and Spicer, 508, 513, 514; Snyder, 29)
18 October 1693
The territorial division between Burlington and Gloucester courts in the Indefinite Counties Area of West New Jersey was restored to its pre-1692 configuration, still unmappable [not mapped]. (Snyder, 29)
17 May 1694
West New Jersey converted Burlington, Gloucester, and Salem courts into counties with the same names, but their boundaries remained incomplete and unmappable [not mapped]. Assunpink Creek was officially designated the boundary between BURLINGTON (and, therefore, the Indefinite Counties Area) and Non-County Area (West); Non-County Area (West) was attached to BURLINGTON [not mapped]. The Indefinite Counties Area gained from CAPE MAY when GLOUCESTER gained from CAPE MAY. CAPE MAY remained the only county in the southern part of West New Jersey with complete and clear boundaries. (Snyder, 2931)
25 May 1700
Within the Indefinite Counties Area of West New Jersey, SALEM gained non-county territory west of CAPE MAY; boundaries of SALEM remained incomplete [not mapped]. (Leaming and Spicer, 574; Snyder, 30)
17 April 1702
Proprietors of East and West New Jersey surrendered to Queen Anne their rights to govern their colonies, and the two colonies were united into the single royal province of New Jersey. No change in counties. (Pomfret, Colonial New Jersey, 87; Snyder, 13; Swindler, 6:439445, Van Zandt, 79)
21 January 1709/1710
BURLINGTON gained from Non-County Area (West); Non-County Area (West) detached from BURLINGTON. GLOUCESTER and SALEM gained from CAPE MAY. Boundaries of BURLINGTON, CAPE MAY, GLOUCESTER, and SALEM were complete and clear; Indefinite Counties Area eliminated. (Paterson, 24; Snyder, 3032)
BERGEN gained from ESSEX; SOMERSET gained from MIDDLESEX; MONMOUTH exchanged with MIDDLESEX. (Paterson, 23; Snyder, 3032)
Two segments of ESSEXs boundary with Non-County Area (West) must be estimated and have been plotted following John P. Snyders interpretation. (Snyder, 3031)
11 March 1713/1714
HUNTERDON created from BURLINGTON and Non-County Area (West). The non-county area was eliminated. (Paterson, 4; Snell, 196; Snyder, 32)
15 March 1713/1714
MIDDLESEX gained from SOMERSET. (Paterson, 45; Snyder, 32)
1714
SOMERSET fully organized, detached from MIDDLESEX. (Snell, 568)
25 July 1719
New Jersey and New York agreed on the location of the northwestern terminus of their boundary, to be called Station Point, on the Delaware River about the parallel of 41 degrees, 40 minutes north latitude, as specified in the 1664 deed from the Duke of York. The location of Station Point was demarcated but the line from there to the Hudson River was not surveyed [no change]. (Snyder, 13)
15 March 1738/1739

1 September 1773
BERGEN lost to ORANGE (N.Y.) and SUSSEX lost to ORANGE (N.Y.) and ULSTER (N.Y.) when King George III approved the boundary between New Jersey and New York, as determined by a commission appointed in 1769 at the joint request of the two colonies after decades of dispute. Line defined as running from the junction of the Delaware and Neversink rivers, a spot several miles south of the terminus selected in 1719, to the Hudson River at the parallel of 40 degrees north latitude. The boundary was demarcated in 1774 and, despite small adjustments later during resurveying and a New Jersey claim to Staten Island, it has remained unchanged to the present. (Pratt, 2:789; Snyder, 1314; Van Zandt, 76)
