Thomas settled in the Parish of West Haven, CT in his native town. His home was on the north side of what is now Main Street, a little east of Campbell Avenue, near the Green, but he also owned considerable farm land towards the Sound. He was engaged in farming and is described as "husbandman" in the public records of that time. He was elected a selectman of New Haven in 1715 & 1716. He was among the first members of the West Haven Congregational Church, organized in 1719, and became one of it's first two deacons an office which he held until his death. In 1733 his name heads the church fund with a donation of $ 130, the largest amount subscribed by any one person.
