The Society of the Cincinnati was established in 1783 by and for the officers in Continental Service of the American Revolutionary War. It was organized into fourteen constituent societies, one of which is the Massachusetts Society. Eligibility was based on the officer's length and terms of service.
Membership in the Society of the Cincinnati was extended to the officers of the Continental Army – as well as Continental Navy and Marine officers – who had served until the end of the war, plus those who had been declared no longer needed by acts of Congress and those who had served honorably for three years during the war. Also eligible were the oldest male lineal descendants of officers who died in service. The officers of the French Navy and Army who served with the American Army were also entitled to join.
A free online database from the New England Historic Genealogical Society contains information on those Massachusetts officers eligible for membership. David Lambert, a staff genealogist at the society, has been researching hundreds of Revolutionary War officers and has created a very impressive online database containing the results of his studies.
This database focuses solely on those Massachusetts officers known to be eligible for membership. Absence from this list does not conclusively exclude eligibility.
