Maggie: If I had some dates for your James McGehee, that would be helpful. There is a James Matthew McGehee listed on page 177 of Vol.III: b.2/6 Feb.1861; d.26 July 1945; a cattleman in TX
His father is shown as James Myles McGehee b.18 Nov 1826 Quitman Co, GA; d. 26 Aug.1882 TX; buried in Dallas, TX; 34d Lt. Co.E. 3rd Rgt GA Cavalry CSA; moved to TX in 1880. Married Sarah Jane Lowe.
Hope this helps.
