Alternate place of birth: Scrooby, Nottinghamshire, England
Despite ongoing and repeated tradition, and claims by an early genealogy compilation,, there is no documentary evidence that Robert was the son of Richard Jackson and Isabella Maltby. The theory may have been based on the fact that Richard Jackson is said to have owned a tract of land at Southold, Long Island, as early as 1640.
Richard and Isabella have, therefore, been detached as his parents, and Robert's birth place has been made more general.
Note: Robert had no children named Richard or Isabella.
The earliest record of Robert Jackson in the New World is about 1644 in Hempstead, Long Island, New York. Many secondary sources claim he came to Long Island by way of Massachusetts, then Connecticut:
"The settlers of Hempstead are supposed to have come from England with the New Haven Colony under the leadership of Gov. John Winthrop and Sir Richard Saltenstall, and before coming to Long Island in 1644, had previously settled at Watertown, Mass., and Weathersfield and Stamford, Conn. They were accompanied by their minister, Rev. Richard Denton, a graduate of Cambridge, who came with them from England. The name of the settlement is said to be from Hemel Hempstead, in Hertfordshire, whence they originally came."
"Following is a copy of a record written by Chalon Lemuel Jackson: 'Robert Jackson born in Scotland in 1621, came to Boston, drifted south through Connecticut and Rhode Island into Long Island, laid out the City of Hempstead..." (Thus a second reference to being Scottish.)"
But no contemporaneous record of him in New England -- or on any passenger list -- is extant.
"Hempstead was first settled around 1644 following the establishment of a treaty between English colonists John Carman and Robert Fordham and the Lenape Indians in 1643. Although the settlers were from the English colony of Connecticut, a patent was issued by the government of New Netherland after the settlers had purchased land from the local natives."
Marriage and family
One source indicates that Robert Jackson's 1683 will calls his wife Agnes, daughter of William Washburn. But examination of the actual will gives no indication of her maiden name.
An analysis of Robert's wives was published in 2000, concluding that while Robert was certainly married to a daughter of William Washburn (her name is not known), so it could not have been a daughter named Agnes, who was deceased in 1659, as Robert's wife Agnes was still alive in 1683.
“Sara, daughter of Robert Jackson” was named in the 1657 will of William Washburn, to whom he gave “one yearling heyfer.” Jackson protested the will of his father-in-law, William Washburn, before probate in 1659, because Washburn had named only one of the two daughters of his late wife, in his will.
The article also makes the case for Robert's having married in England before migrating to the colonies. He later married the widow Agnes Puddington, maiden name is unknown.
The order of birth of his children is uncertain, although the four children mentioned in his will are in the following order:
Mary Jackson, born say 1642, probably in England, married John Ferris, of Westchester County, New York, in c1661. He was born c1639. She died in 1704, and he remarried to Grace (___). He died testate in 1715 in Westchester Co., NY, his will dated 9 May 1715.
John Jackson, born say 1644, probably in England, married Elisabeth Seaman, daughter of Capt. John and Elisabeth (Strickland) Seaman, of Hempstead, in ca. 1668 in Hempstead. She was born in 1647. He died in 1725. They had six children.
Samuel Jackson, born in, say 1646, was married and had children by 1683.
Martha Jackson, born ca. 1649, married Nathaniel Coles, of Oyster Bay, Long Island, son of Robert and Mary (Hawxhurst) Coles, on 30 Aug. 1667 in Warwick, RI, but she died in 1668, and he remarried to Deborah Wright in ca. 1669. He was born in 1640, and died in ca. 1712. Martha (Jackson) Coles had one son.
Sarah Jackson, born, say 1653 in Hempstead, named in the will of her grandfather, William Washburn, in 1657, married Nathaniel Moore, son of Thomas and Martha (Youngs) Moore, in ca. 1675, probably in Hempstead.
(Unnamed daughter), born say 1655 in Hempstead, as indicated by the wording in the lawsuit that Robert Jackson filed against the estate of William Washburn on behalf of his two daughters, probably died unmarried before 1683 when Robert Jackson wrote his will.
"In 1656, Robert Jackson and others wished to improve their labors, and applied to the Dutch Council for permission to begin plantations toward Carnarsie and Jamaica. They also applied to Governor Stuyvesant for more liberty and for representative government."
"After the Dutch surrender to the English on August 27, 1664, the colony was renamed New York. Governor Nichol called a convention of two delegates from each Long Island town to frame a code of laws to govern the colony. This convention was held at Hempstead February 28, 1665, with Robert Jackson and John Hicks representing Hempstead. The code of laws [Duke's laws] written at this convention remained in force until after the Revolution. Robert's will, dated May 25, 1683 and proved October 13, 1685, is found in Will book A in Queens County, NY."
4 Dec 1666: Robert Jackson and John Jackson were recorded as freeholders of Newtown.
