He and wife Jane with four sons and daughters aged 11 to 1 year sailed from Weymouth on or near 20 Mar 1634/5 on the ship "Marygold" with Rev. Joseph Hull's Company of families who were going to settle together in New England to form a town. They came ashore at Dorchester the 7th of June 1635, remained a "fortnight" and then they went to the place now called Weymouth and built a house, etc.

The family settled in the northern part of Weymouth on the Tide-water. Ten acres were granted to Thomas in the first division, and 30 acres in the second, in that part of Weymouth called "Old Spain." They lived next door to Thomas' sister Rebecca and her husband Clement Weaver. Thomas was a grantee of Rehoboth, Massachusetts in 1643 although he forfeited the grant two years later by remaining at Weymouth. He owned the salt meadows at Kingman's Neck.

Thomas was made a freeman of the Massachusetts Bay Company in May 1645 and served as selectman at Weymouth six times (1641-1654). In 1649 he was appointed a member of a commission to lay out a highway from Weymouth to Dorchester.

Thomas made a statement November 7, 1666, giving his age as 77 years. 349
