The General John Thomas House at 156 Main Street in Kingston, Massachusetts, is significant as a pre-Revolution Georgian style residence and for its connections with a notable Patriot. General John Thomas (1724-1776) was born in Marshfield and later studied medicine, completing his studies in 1746 at the age of 22. He practiced medicine until being appointed in March 1746, as assistant surgeon by Governor William Shirley in Samuel Waldo’s regiment. Liking military service, in 1747 he traded his post as surgeon for that of a lieutenant. By the time of the French and Indian War he had risen to colonel in the militia. After the war, he married Hannah Thomas in 1761 and either built or moved into this house in Kingston, where he practiced medicine. In the years leading up to the American Revolution, John Thomas was a Brigadier, and briefly resigned from the ranks, disappointed that while four major generals were named, he was not on the list. Congress was then trying to name no more than one major general from each state, and Artemas Ward was given preference. George Washington implored him to remain, and John Thomas returned to service. The Congress resolved that he would be given precedence over all other brigadiers in the army. On the night of March 4, 1776, he led his division to fortify the Dorchester Heights, overlooking the south harbor at Boston, by using cannon that Henry Knox had brought from Fort Ticonderoga. From that position, he threatened the British fleet and the British were forced to withdraw, evacuating Boston on March 17. Thomas was finally named a major general. Soon after, Thomas was assigned to command in Canada and take charge of the Canadian invasion. He joined the army besieging Quebec and remained there until he died of Smallpox in June 1776, not living long enough to see a free America. The John Thomas House is a lasting and important physical vestige of his legacy.
