Green was born in 1796 in Massachusetts. By the accounts published after his death he had spent his adult life as a burglar, highway robber and horse thief across New England, and had killed a number of men in the course of it, by beating and shooting, between 1817 and 1821.
He was convicted of the murder of a fellow inmate at the Massachusetts State Prison and hanged at Boston on April 25, 1822.
The one killing he was executed for is documented. Everything else comes from a genre that flourished in early nineteenth-century America: the published confession, sold as a pamphlet at or after an execution, in which the condemned man's whole criminal life was set out at length for an audience that paid for it. Green's was printed and sold, and it is the source of the word numerous that this roster carries in place of a count.
There is no way now to test any of it. The pamphlets were written by editors and clergymen as much as by the men whose names were on them, and they were commercial products. The entry records the execution and the existence of the confession, and the count should be treated as unknown.
