Established just one month after the founding of The Society of the Cincinnati, the New Jersey Society was the third of the constituent societies formed and the first to be organized away from the main army cantonment in New York. On June 11, 1783, Brig. Gen. Elias Dayton called a meeting of the officers of the New Jersey Line at Elizabethtown, New Jersey, to consider the proposals of the Society's Institution. After some deliberation, they voted to become members and elected their state officers: General Dayton, president; Lt. Col. Jonathan Forman, vice president; Rev. Andrew Hunter, secretary; Maj. Richard Cox, treasurer; and Dr. Ebenezer Elmer, assistant treasurer.
