Ralph and Neva's children were: Ralph G. b. 3 Aug 1907 Dallas, Polk, OR d. Mar 1978 Bend Deschutes, OR Alice b. 1909 Frank H. b. 1911 d. Washington Co., OR Virginia b. 1914 d. 1998 Howard Campbell b. 16 nov 1915 Falls City, Polk, OR d. Hereford, Cochice, AZ
I am thinking that Ralph's parents are Benjamin and Lila Adams. 1880 census has them in Chicago, Cook, IL.
Ralph and family have lived in WA and ID before settling in OR.
