H I looked for your names in my Seb. Co. cemetery books, but did not see any with the dates you had. There is a Jesse Smith died Talihina,Ok death 04/08/36 born 2/20/07 buried Summerfiled,Ok. that is the closest to the ages you gave. I do not see them in a cemetery book that I have for Talihina cemetery at all, others, but none of your names. I also looked thru the Cameron & Vaughn cemeteries in that part of the area, none there. If Jesse was not in the 1870 with her and the boys, he must have passed on already. See if you can find them in 1860 census index if they are not in AR, look at the last childs bith year, and they were in that state when he died no doubt. Alice could have remarried? I have found a couple of the sons marriages in Seb Co. Marriages 1873 -1880 Smith, Isaac H. - 23, Perlina Burnett 17, Sept 11, 1879 Smith, Martin B. 24- Haley Bynum 24 Nov 29, 1876. See if someone on the site, can do a lookup for 1880 soundex, and see if she is in Ar. under Alice Smith Hope some of this helps, There is Logan & Scott Co's right there also. I did not see them in Scott Co. cemetereies If I can help any more let me know Mildred
