Born ‎1607 at North Kelsey, Lincolnshire, England, United Kingdom, died ‎1661 at East Haven, New Haven County, Connecticut, United States‎, age 53 or 54 years

The first record that we have of William Ludington is of his being before the Court, in Boston, in August 1640. He was charged with having built a house in Malden outside the limits set by the Court. This limit had been set on account of fear of trouble with the Indians. He was fined ten shillings, but the fine was remitted and the limit discontinued because it was decided that there was no longer danger to be feared from the Indians. Though that is the first time that he is mentioned in the records there is good reason to believe that he came to Boston on the ship, "Hector," with the company of Eaton and Davenport, that arrived on June 26, 1637.
William Ludington was a brother-in-law of Matthew Moulthrop. It is almost certain that they came to America together. When the first settlement was made at New Haven the name of Matthew Moulthrop was put on the list of land holders. The space after his name was left blank. Al the others had the amount of land they were to have filled in. This shows that Matthew Moulthrop had come with the company, and indicates that he had not come from Boston, but was expected to come. He did come and was a resident there when the next record of the inhabitants was made.
As to why William Ludington did not go to New Haven, the question is perhaps answered by noting the fact that Thomas Ludington was born during the time that the New Haven company was staying in Boston, before they went on to New Haven. At any rate William Ludington did remain in Malden for twenty years, then he went to New Haven. The last account of him in Malden was in 1660, when he served on the jury.
In Connecticut, he bought a house on the west side of the river, at Branford, near the iron smelter. Some accounts say, that he owned an interest in the iron smelter. That is not likely. The iron smelter was built by the towns of New Haven and Branford. Some of the men, who furnished the labor and material to build the smelter took their pay in shares in the smelter, but William Ludington was a newcomer there and was not likely to have an interest in the smelter. He was a weaver, and like a good business man he went to the place where there was likely to be a demand for the wares that he would have to sell. When his estate was before the probate court, the next year, the Judge asked the widow if there was a will. She answered that she did not know. That she had been from home at the time. Matthew Moulthrop said that there was no will. Matthew Moulthrop and John Cooper took an inventory of the estate. They made no mention of an interest in the smelter.
A petition for the administration of the estate was filed in Middlesex Co., Mass. (Boston). By John White, on Oct. I, 1661. That gives the approximate time of the death of William Ludington.
There is mention of a few acres of land, on which his house stood. It was on the west side of the river, in what was called East Haven. There was also mention of 100 acres of land belonging to the estate, but its location is not given.
An inventory of his property has been preserved. It shows that he was still in the business of a weaver, and that he was comfortably well of.
