I just posted an old death notice for Evans Caroline M. DICKINSON, widow of John DICKINSON, the editor of Shreveport's first newspaper. It lists one survivor, a daughter, Mary A. LINDSAY of Shreveport. This was scanned from an original issue (NOT microfilm!) of the Daily Picayune dated January 6, 1912. You can see it online here:http://theoldentimes.com/ecmdickinson12la.html
I hope it's helpful!
