The Campion Alumni Directory published in May 1928 actually covers from 1882 (note NOT 1884) to 1930.
Here is the Alumni Directory published in 1940-41 year which was the 400th anniversary of the Jesuits and the 60th anniversary for Campion... Directory I covering 1880 to 1940-41. Actually it also contains alumni prior to Campion including St Johns College back to 1871.
Bro Staber, S.J. and Mrs. Emma W. Bouzek compiled a Directory II in June 1978 which covered 1940-41 to 1974-75 and includes those who would have graduated in 1978.
Bro Staber, S.J. compiled this Directory of All Employees from 1880-1975(1978). It includes Jesuit Priests, Jesuit Scholastics, Jesuit Brothers, Lay Person Teachers, Professionals, Secretarial, Business and Consultant Personnel, ROTC and SATC Personnel. I don't think it includes any Students who had odd jobs around campus.
