Re: Blankenship/Civil war/Confederate
Is Houston Blankenship b. TN, (from IL) on your list of Civil War soldiers.He also lived in AR, MO, & TX.He lived in Wilson Creek, MO in 1860.
His brothers are Marion Frances Blankenship d. 1863 of IL & TX and John E. Blankenship d. 1864 of IL. I'm guessing they died as a result of the war.
None of these men have been found on an 1870 census in any of the above mentioned states.
