Another Eureka moment!
I was googling some of Cordelia Jones' older family names, ie Hardy Jones and Mary Margaret Peggy Mears and I found some Roots.com links. I've summarised what I've found below, but have a go at googling Hardy Jones and Mary Margaret Peggy Mears- there is a ton of info which I haven't processed yet.

http://www.couchgenweb.com/arkansas/lee/biog-lee.htmH. M. Jones, recognized as one of the well-to-do and enterprising farmers and stock raisers of Independence Township, was born in Limestone County, Ala. His father, Kimbrough Jones, was also a native of Alabama, and was married in 1846, to Evaline Weatherford, who bore him eight children: Sally (Mrs. J. P. Farrel, of Marianna), Betty (Mrs. Beauchamp, now dead), Margaret (the wife of J. D. Brown, of Marianna), Fannie (now the wife of Mr. Beauchamp, of Marianna), Emma (deceased), S. W., Dixie (Mrs. Harden) and H. M. (the subject of this sketch). Mr. Jones was a successful farmer, and in 1868 moved to Arkansas, settling in Lee County, where his death occurred two years later. Mrs. Jones is now living with her children in Marianna, and is a member of many years' standing of the Methodist Church. Mr. Jones settled the land owned by his father and which is now operated by him. After the father's death he assumed charge of his mother's family and the management of her estate, where his intuitive sense and excellent business qualifications were given a wide scope. His farm consists of 100 acres of valuable land, with eighty acres under cultivation, and bears evidence of careful and unceasing attention. In his political belief he is a Democrat.
