I can't find the 1870 census. Benjamin was in the Company I, 11th Arkansas Infantry, captured at Island No. 10, died at Camp Douglas in Chicago, Illinois as a prisoner of war. Ellen Evans Cash. Evans was her maiden name and she married a Cash and he died...I think in Fayette County Tennessee. Her father was John Evans, mother was Deborah. You should be able to find her in the 1850 census in Hot Springs Arkansas with a couple of the Cash children and her Mother Deborah and youngest brother Robert David Evans.
