The house's construction date and original owner are not known. It was purchased in 1748 by Reverend Solomon Williams, who gave it to his son William in 1755. William (born 1731) was trained at Harvard College, and saw provincial militia duty in the French and Indian War in 1755. He settled in Lebanon that year, and embarked on career as a merchant, jurist, and politician. He served in the provincial assembly 1757-76 and the state legislature 1781-84. He was a steadfast supporter of independence during the American Revolution, working closely with his father-in-law, Lebanon native and Governor of Connecticut Jonathan Trumbull. Williams personally funded Connecticut militia that captured Fort Ticonderoga in 1775. He was elected to the Second Continental Congress, where he signed the United States Declaration of Independence and the Articles of Confederation. He was a delegate to the 1788 state convention that ratified the United States Constitution.
