The 350th Anniversary of Thomas Munson coming to America was celebrated at Yale University in New Haven, Connecticut in August of 1987. Many members of the Munson family were benefactors for establishing Yale University.
There is a Thomas Munson Family Association which any Munson family member may join.
Information on the Munson family is available in The Munson Record: A Genealogical and Biographical Account of Captain Thomas Munson and His Descendants, by Myron A. Munson, M.A., 1895. There are now 5 volumes of this Munson family history and copies may be found in larger libraries across the country.
Thomas Munson (1612-1685) first appears in America in records of Hartford, Connecticut in 1637 as a member of the militia unit engaged in the Pequot Indian War. In 1639, he signed the Fundamental Agreement at New Haven where he established his permanent home. His life is well documented in The Munson Record Volume I and the Connecticut Colony records. The evidence is persuasive that the Thomas Munson who was recorded as being baptized in St. Nicholas Church in Rattlesden, County Suffolk, England on September 13, 1612 was the same man who later distinguished himself in the public affairs of colonial New Haven. The principal tie is the age listed on his gravestone.. aged 73 years, which links well with the baptismal record. The Church records document that the Thomas Munson of Rattlesden was the son of John and Elizabeth Munson. John was baptized 14 Oct 1571 and was buried 26 Nov 1650. Elizabeth was buried 3 Jan 1634/5. John was the son of Richard and Margery (Barnes) Munson. Richard was buried at Rattlesden on 3 Dec 1590, while Margery was buried there 7 Feb 1622/3.
