Can't help out too much here. I did find a marriage record in Wyoming Co., WV for Roy and Gertrude as well as Roy's sister Joan Ruth Acord. Both of these listed their parents as JOE ACORD and OLA ACORD COOK.
I have not found Joe in the 1930 census record anywhere in WV.
Joan Ruth first married a Frank Brooks on 8/18/1949 and then married a Robert Carrol Cook on 11/6/1954 where Joan listed her father's name as L. J. ACORD.
