The three databases that will be most useful in finding scholarly articles for the rhetorical biography you will be writing are MLA International Bibliography (MLAIB), Communication and Mass Media Complete (CMMC), and Annual Bibliography of English Language and Literature (ABELL - provides broader coverage of British and British Commonwealth authors and British journals than does MLAIB, so if you are working with a woman who is not from the U.S., this may be a helpful source). I've provided links to each in the column to to right.
