Well, you might find this letter I have interesting... It is dated June 8, 1885 and addressed from Purley NC (in Caswell). It is addressed to Mary A. Travis in Macon County MO AND it if from Mattie W. Gatewood. Mary Travis was apparently Mattie Gatewood's cousin. It references a whole bunch of people and their conditions and some marriages and deaths, etc.
I would be happy to send you a scan and transcript, just drop me an email
