In the last volumes of his Records a/the English Province a/the Society of Jesus (1877-83) Brother Henry Foley included short biographical sketches of the members ofthe province from the first English Jesuits to the time of writing and also of the members of the Scottish and Irish Jesuit missions which were not part of the English province. As more sources, particularly in Rome, have become available since Foley's time it is now possible to compile more detailed biographies and this has been the object of this volume. The list of biographies (some 1560 of them) includes those who entered the Society of Jesus between January 1st, 1650 and the Catholic Emancipation Act of April 1829. More research needs to be done on the period before 1650, and after 1829 information is readily available in more easily consulted sources.
