Those obits that Shortie found for you are a great help.
I found James's sister Osie in Buckhannon (Upshur County), WV. Her husband's name was Carmen. However, it seems that this was a later marriage. Osie married Howard Norvell Campell in Upshur Co. in 1939. She was 20 (b. c. 1919 in Webster County). Her parents were O.C. Mitchell and Delilah Mitchell.
Go to the WV vital records site directly to find other records for this family. You will find Oliver's marriage to Delilah Dilly and probably more. Images are freehttp://www.wvculture.org/vrr/va_select.aspx
I found this family in 1920 census in Webster Co.http://interactive.ancestry.com/6061/4389746_00495/37787775?...
His father's name was Oliver. James is listed as 2 years 11 months. Osie's name was indexed as Ora. Edna is also listed.
This should give you a good start on James's family.
