Jonathan Trumbull was born on October 12, 1710, in Lebanon, Connecticut, the son of Joseph Trumbull and Hannah Higley Trumbull. His father was a prosperous merchant and farmer, and the family belonged to the respected Congregational society of eastern Connecticut. Jonathan was prepared first for the ministry rather than commerce or politics. He attended Harvard College, graduating in 1727 and earning a master’s degree. His education emphasized classics, theology, logic, rhetoric, and moral philosophy. Trumbull studied for the ministry and was licensed to preach, but the death of an older brother changed the family’s plans. He returned to Lebanon to assist his father’s mercantile business. Trading taught him accounts, credit, supply, and negotiation across New England and the West Indies. These practical skills later proved crucial during wartime government. In 1735 he married Faith Robinson, daughter of a Massachusetts minister. Their children included the painter John Trumbull and public officials who continued the family’s influence. Trumbull entered the Connecticut assembly and gradually advanced through colonial office. Congregational faith, commercial experience, and the colony’s tradition of elected government shaped his political outlook. Unlike most royal governors, Connecticut’s leader derived authority from local election. Before becoming the only colonial governor to remain in office on the Patriot side throughout the Revolution, Trumbull had been shaped by Harvard theology, family bereavement, abandoned ministerial plans, mercantile responsibility, marriage, fatherhood, and decades of elected service. His ability to supply Washington’s army grew directly from business habits learned after leaving the pulpit path. Religious duty and logistical competence were equally important parts of his early formation.
