History of Lay Undergraduate Theology

Does anybody know of good sources for the history of the study of Catholic theology by lay people before the twentieth-century?  I am thinking of Continental Universities before and after the Revolution, and especially English laymen who studied in Europe.  Moreover, I would be interested to know about the curricula of American Universities in the late nineteenth century.  My impression is that it was more or less clerical at first, but I could be wrong.
