Henry Jackson was probably the man who came [from London, England] in the ship Elizabeth and Ann in 1635, aged 29, having taken the oath of allegiance & supremacy to the crown, & brought a certificate from the minister & justice of the peace, in the place he resided in England, (not mentioned) of his conformity to the Church of England, & that he was no subsidy man. (Hotten's List of Emigrants to America.) In the same ship came Robert Hawkins, Nicholas St. John & several of the Whitney family. He was at Watertown [Massachusetts] in 1637, & was, says Savage, "one of the lessers of the fishing grounds of that place." He was at Fairfield in 1648, where Feb. 2, 1648/9 he made an agreement with the town to erect a grist-mill on the stream running into the west side of Uncoway River, which he sold in 1653 to Samuel Morehouse. His home-lot was bounded n.w. with Nathan Gold's pasture lot, n.e. the Unocoway mill-creek at high water-mark, s.e. highway, & s.w. with his own land. He removed after selling the mill, to Pequonnock & purchased, the house & home-lot of Thomas Wheeler jr. He was made a freeman 10 Oct. 1669 and was one of the dividend land holders of the town. His will is dated 11, Nov. 1682, in which he provides for a wife (Christian name not mentioned); to son Moses housing & Ludlow's lot, except one acre at Pequonnock, and in Uncoway Indian Fields; ¼ of his pasture-lot, building-lot & long-lot: to the children of his deceased daughter Hannah, who had married Philip Galpin, £5 each when of age; to s. Samuell land previously deeded him, several parcels of land and ¼ of his pasture-lot, building-lot & long-lot: to grandson Moses Jackson 4 acres at Try's Field, bounded n.w. with highway that goes through the filed; s.w. John Roots, s.e. the Indian Field, n.e. land that was Richard Fowles, also his Compo allotment: to s. John of his pasture-lot, building-lot & long lot; to his grand-son Samuel Jackson, his loom & "all things thereto belonging; & to his wife his best feather-bed & bedstead, curtains & valance, & all the furniture thereto belonging; the bigest kettle & his house in town, & the least kettle, the middle iron-pot, the bell-metal skillet, the red cow and her calf, also the third part of his pewter dishes, spoons, and beer vessels in his house at Pequonnock, the great chest & her own chests, the use of housing & lands at town, with its table, stools & chairs, with any other of the house-hold estate, except the axe, that is commonly called Dina's axe," ¼ of table linen, & if left alone, the old, negro woman to care for her; & £6 per annum from sons Moses & Samuel; to s. Joseph's five children, under the guardianship of son Samuel £5, each of them to receive 20 shillings when of age; to Major Nathan Gold & Josiah Harvey, as over-seers of his estate £20. Upon the death of his wife the house at Fairfield & all things belonging to it, were to be divided between son Joseph's five children allowing the eldest son a double portion. He requests that the shares of his s. Joseph's widow in her father-in-law George Goodwin's estate, be paid over to the estate of Joseph's children. He entailed all his estate to his surviving male heirs, in case of the death of any one of his sons.

There were lands, probably rights in the common or undivided lands, not disposed of in the will, and many years later, on 13 Jan. 1718/9, administration was granted to Henry's grandsons John and Robert Jackson, and distribution was ordered to the legal representatives of the sons John (the eldest), Moses, Samuel and Joseph. The distribution, dated at Stratfield 3 Jan. 1720, named the heirs of Samuel Jackson as Daniel, Johathan, Ebenezer, and Gabriel Jackson, Hannah Jennings, Deborah Fairchild, Rachel Lyon, and Abigail.
