Thomas moved from Woburn to Billerica about 1667 and settled, it is believed, on a large tract of land about 900 acres in the east part of town called the Cambridge School Farm, a little west of the Shawshin River and north of the present Boston Road. He was a soldier in the company of Capt. Samuel Gallup in the land expedition to Canada by way of Albany in 1690, which utterly failed. He was deputy from Billerica to the General Court of Massachusetts in 1703 and 1704. Deeded land to son Andrew, Oct. 14, 1705.
