Justus Barnum served during the Revolutionary War in Captain Benedict's Company, Colonel Bradley's 16th Connecticut Regiment. (Could Captain Benedict be the father or grandfather of Justus' wife Mary Benedict?) Justus enlisted Aug 11, 1776. The Genealogical Record of the Barnum Family calls him Captain Justus; a handwritten note found in a copy of that same source states that Colonel Justus of Danbury died May 25, 1825 in New York.
The Barnum Family, 1517-1907 mistakenly shows him as a son of his grandfather.
The US Census of 1790 shows Justus Barnum, with two free white males 16 years and upwards, two free white males under 16 and four free white females, living in Danbury, Fairfield County, Connecticut; the 1810 Census shows Justus in Norwalk.
