Plainview Indians 1941

I found an old trunk in what used to be my G-Grandparent's barn(Gann side of my Family). This trunk had very old personal letter's and postcard's saved from back when Oklahoma was Indian Territory. The letter's were written by different family member's from Arkansas to Indian Territory. The oldest letter I think is dated 1884. I also recently met a cousin who had my G-Grandmother's(on my Walker side) old Picture box, He was kind enough to let me bring it home and scan everything inside. My Grandmother(Elva Joy Walker(Gann) also introduced me to a Cousin named Theola Walden Baker who compiled "The Gann Family 1705-1996". Once I 1st read it and with all the above, I've been "hooked" ever since! I'm researching names on my Dad's side of Bailey, Gann, Green, Dooly, Moreland, Spann, Smart, Trout, and Walker. I'm also researching names on my Mother's side of Baty, Mace, Morris, Mixon, and Oakley. Thank You in advance for any light you might shed on my Family Tree history yet to be discovered by me. Sincerely, T. D. Walker
