Although Caraman's name is familiar to Catholics, his energies were spread among may activities, so he is not easily pigeon-holed. Apart from his religious vocation, he was a writer. His research was original and valuable, not just on the early English Catholics, but on Jesuit history (the missions in Paraguay, Ethiopia and Tibet). He forwarded the cause of the canonization of the English martyrs, and, more surprisingly, spent years in Norway trying to establish a Catholic toehold there.
