TRUMBULL, Jonathan, statesman, was born in Lebanon, New London county, Conn., Oct. 12, 1710; son of Joseph (d., June 16, 1755) and Hannah (Higley) Trumbull; grandson of Capt. John Higley of Windsor and Simsbury, and of John and Deborah (Jackson) Trumbull of Suffield, Conn., and great-grandson of John and Ellenor (Chandler) Trumbull.  John Trumbull came to America about 1637, from Newcastle, upon Tyne, England, and settled first in Roxbury, and then in Rowley, Massachusetts Bay colony. Jonathan was graduated from Harvard in 1727; studied theology under the Rev. Solomon Williams at Lebanon, and was licensed to preach at Colchester, Conn.  In 1731 he engaged in the mercantile business with his father, and in 1734, on the death of his elder brother, he joined his father in business.  He studied law; was a delegate to the general assembly, 1733-40; speaker of the house, 1739-40; was appointed lieutenant-colonel in the state militia in 1739, and was repeatedly elected governor's assistant.  In 1743 he established an academy at Lebanon.  He was deputy-governor, 1766-69, and was elected governor in 1769, serving until 1783, when he resigned [p.195] on account of advancing age.  During the Revolutionary war, he was ex-officio chairman of the council of safety; did much toward raising troops for the prosecution of the cause, and was a staunch friend and adviser of General Washington, early assuring him of the loyal support of Connecticut to the cause of American independence, and upholding him throughout the war.  Washington, when in doubt as to his course of action, frequently said, "Let us consult Brother Jonathan," thus giving rise to the name as representing the American people.  The honorary degree of LL.D. was conferred upon Governor Trumbull by Yale, in 1775, and by the University of Edinburgh, in 1787.  He was married, Dec. 9, 1735, to Faith, daughter of the Rev. John and Hannah (Wiswall) Robinson of Duxbury, Mass., and of his children, Jonathan (q.v.) was governor of Connecticut, 1798-1809; Joseph (q.v.) was the first commissary general of the Continental army; David was commissary of the colony and assistant commissary under his brother; John (q.v.) became a noted historical painter; Faith married Gen. Jedidiah Huntington, and Mary married William Williams, the signer.  In 1896, on the chimney above the fireplace in the old war office at Lebanon, the Connecticut Society Sons of the American Revolution caused to be erected a bronze slab on which is inscribed:  1775-1783. Lebanon War Office.  During the War of the Revolution, Governor Jonathan Trumbull and the Council of Safety held more than eleven hundred meetings in this building, and here also came many distinguished officers of the Continental Army and French Allies.  Their Monument is more Enduring than Bronze.  Governor Trumbull died in Lebanon, Conn., Aug. 17, 1785.
