William Wirt was, I believe, postmaster general of the U.S., and a candidate for president in 1832. An online search should find plenty on him. Harold Cross' "They Sleep Beneath the Mockingbird" is a book on Confederate Generals buried in Mississippi. It has much biographical detail on the Adams brothers. It was publsihed about 6 years ago by the (check the exact name) Confederate Research Center in Murfreesboro, TN. Again, an online search for the title should tell you where it can be ordered.
