Thanks for the links. Those are useful sites, but I don't think they really address my problem.
I tried searching through all of the Chicago Style books and references that I could find, and I did discover one at my local library that mentioned chronologies. It suggested that a chronology be included as back matter, or within an appendix. Defining the chronology as an appendix seems like the best solution to me, but that raises the question of whether or not I would be required to have a table of contents.
So in that case, let me refrain my question: According to Chicago Style, is it "legal" to include an appendix without a table of contents?
