Among the documents Maureen sent me were her grandfather James J. Mulvaney's discharge papers from the Army.

James J Mulvaney WWI Discharge - 2
These show that he entered the Army 28 September 1917, and was honorably discharged 1 July 1919. He was blue-eyed, brown-haired, fair-skinned, and 6 feet 1/2 inches tall. He was, as we know, a Brooklyn-born fireman, and in 1919, he was not yet married to Florence Goggin. He was never an officer, was not qualified as a marksman, was not mounted calvary, and apparently was not involved in any battles, skirmishes, engagements, or expeditions. He had excellent character, and in very faint ink underneath that, his service is described as honest and faithful, with no AWOL and no absences under GO [illegible]. He was entitled to travel pay back to Brooklyn, as well as a $60 bonus as authorized by an Act of Congress, 24 February 1919. He also had 1 silver/bronze victory button issued.
