I am trying to find the parents of ISLEY R. CARICO (bn 1905), ALONZO M. CARICO (bn 1912) and GAINES H. CARICO (bn 1918). They are all listed in the 1930 Scott Co., VA census as the grandsons of Emily M. Carico. I believe Enily M. is Margaret Emily Dockery, the wife of James A. Carico. I have not found ISLEY, ALONZO or GAINES in any 1920 census. Thank you for any help you can give me.
