Since you last corresponded with Nell, I have obtained additional information on this family. George Alexander Shelton was the brother of my husband's great grandfather, William Mortimore Shelton. I have found 3 siblings of George Clark Shelton. They are: James Arty Shelton, b.
Mar. 3, 1880; d. Nov. 12, 1962; Lelia Ann Shelton, b. Apr 7, 1881; d. 12-18-1943 in Ray, Pinel, AZ; buried in Casa Grande Cemetery, Pinal, AZ - Death certificate listed George Alexander Shelton as her father and Percilla True as her mother. You can also view the cemetery marker online. Her married name was Wilson, but I believe she was married prior to Wilson; and Leslie Lee Shelton (M) b. Oct. 11, 1884; d. Dec. 15, 1967; buried in same cemetery as George Clark and James Arty. If you have any additional information I would appreciate it. I am willing to share any information that I have.
