John Vincent, signer of the New Haven Fundamental Agreement, died in 1659; He may have come from Dorchester, England.
He was married to Rebecca ______, probably a year or two before their children were born. Rebeckah Vinson, widow made a will 23 Jan 1676. She appointed John Nash and John Winston as overseers to distribute her estate to her daughter Hannah and Hannah's husband Ebenezer Browne and their children. Samuel Whitehead and Thomas Trowbridge were witnesses. Samuel Whitehead and John Winston took the inventory, valued at £110:14:10, on 13 May 1679.
According to Atwater’s History John Vincent first appears on the colony records in 1638.. He signed the Fundamental Agreement with his mark in the group after the meeting at Newman’s Barn.  He was a freeman of the colony and had an assigned seat in the meeting house 1646 and 1656. Because his wife did not have a seat, it can be assumed she was not a member.
John was not one of the proprietors, all of whom had a certain measure of wealth to start, but he was granted in 1641 a small lot on the bank side by the west creek, and received small lots in the sec and third divisions, indicating his single status. In 1646, he purchased another 5 ½ acres on the Indian side from John Nash. When Mrs. Eldred’s lot in the town squares became available 31 Jan 1648/9, Joseph Nash refused 3 acres that were granted to him there and John Vincon, now the father of two, requested the piece which the court granted to him. John Vincon also sold six acres at the plains to Isaac Beecher 4 May 1652.
Like most of the citizens of New Haven, he received some fines: 1643 1s for coming late to training, 6d in 1648 for not having enough bullitts, May 1650 12d for defective fencing, and Nov 1650, 12d for coming late to training
Committees were also an important aid to running the community. 9 Oct 1648 John was on a committee chosen to consider and debate the problem of swine and fences, because of damage to the crops. Ironically, in April 1649, John Vincon, Joseph Allsop & Andre Low, were complained of and fined for their fence being down. They explained the fence was burned down and they needed help to fix it., the court believed they had ample time and a previous warning, to do something about the fence, “therfore the court ordered that the generall courts order be attended in ther payeing 12d a post for those that be downe, wch is 20 post as Jn° Coppr saith, & that the viewer be pd what is his due, & what damadge beside hath come by it if it be required, & Andrew Low is further fined 12d a post for 12 post that hath bine downe longer, betwixt the two quarters. “ They must have fixed the fence and a 20s fine was remitted 14 May 1649. 
23 June 1659. Brother Vinson beinge taken away, by the hand of God, Brother Thorp was chosen a viewer of the Ox pasture in his stead.
An inventory of John Vinson's estate was taken 10 Nov 1659, by Henry Lindon and Samuel Whitehead. The estate was valued at £90:12:04. The whole estate was left with Widow Vinson until further Order. 
"March 1661/2 It was Ordered that the Estate of John Vinson deceased shall be divided in equall proportion, betwixt ye widdow & her daughter, but the whole to remaine with ye widdow vntil further Order. At this point in time daughter Hannah was still a minor.
John and Rebecca had two children in New Haven. They were baptized at the First Congregational Society of New Haven Church, while John Davenport was the minister.
Hannah Vinson was baptized 28 March 1647; m. 28 Mar 1667, (1666/67) in New Haven, Ebenezer Brown. They were married by Mr. Matthew Gilbert.
John Vinson was bpt 8 Oct 1648;, d.s.p. John was not mentioned in the distribution of his father's estate
