From the Richmond Dispatch, 10/12/1863, p. 2, c. 3
THE RECENT EXECUTION OF A SPY. – Admiral Porter is out in a letter in the Philadelphia Inquirer, in which he states that Spencer Kellogg, recently executed in Richmond as a spy, was Spencer Kellogg Brown, a son of Orvill Brown, and grandson of the famous John Brown. He avers that he was one of the most intelligent warrant officers in the U. S. Navy, and that he was not a spy. Brown will be recollected by the citizens of Charlestown as the young grandson of John Brown who came on to that town with Mrs. Brown before her husband's execution. Orvill Brown, the father of the spy; was killed in the melee at the Harper's Ferry arsenal.
