The standard compilations of Massachusetts Revolutionary and Civil War veterans are Massachusetts Soldiers and Sailors of the Revolutionary War, prepared and published by the Secretary of the Commonwealth, 1891, and Massachusetts Soldiers, Sailors, and Marines in the Civil War, compiled and published by the Adjutant General, 1931. These books, available in many libraries, offer help in determining when and with what regiment war veterans served. Several commercial genealogy websites also provide electronic access to the information gathered for these volumes.
