by A. J. (Augustine J.) O'Reilly
Very little biographical information about A. J. (Augustine J.) O'Reilly could be confirmed from the sources reviewed, but his published work shows him as a Catholic author writing in the nineteenth century. Catalog and library records consistently connect him with historical and religious books centered on the early Christian world.
Among the works reliably attributed to him are The Martyrs of the Coliseum, The Victims of the Mamertine, and Alvira: The Heroine of Vesuvius. These titles suggest a strong interest in Christian martyrdom, Roman history, and morally serious fiction written for readers drawn to faith-filled historical narrative.
