Welcome to wikitree. Hopefully, we can help you find some information. Sorry to hear about your husband. It is so hard to lose people with the way things are right now.
Family search has quite a few sources for James Orrin Bruce, b 1891 possibly WV, d 1978 in FL, WW I vet. so that might match to your possible birth of mother in WV.
I found a 1940 Census of Margret Hickman, b 1931, with parents Shirley (male) and Edith in Grantsville, West Virginia. Mother Edith would have been 16 when she had Margret - https://www.familysearch.org/ark:/61903/1:1:K7H1-ZYL
Then there is a Marriage of Margaret Hickman, age 19, Jun 8 1949 in Calhoun, WV to Carl Bell, so that would be 2 months after Clifford was born. She could have gone to FL to have him. Parents of Margaret match the census above. Carl was 21, parents are listed also - https://www.familysearch.org/ark:/61903/1:1:FR6P-175
I found a child of this couple who died Apr 1957 in Calhoun, WV. - https://www.familysearch.org/ark:/61903/1:1:NMMT-NFC
Found a Peg Bell Find a Grave, b Nov 1926, d Dec 2000 Grave ID - 85849322
Found a Margaret Hickman who divorced Carlton Camp Jun 1973 in Orange California - https://www.familysearch.org/ark:/61903/1:1:VPB4-5B6
I found a few Margaret Hickman, b 1910, 1911, 1924 in Florida with 1910-1930 census
Keep in mind that Carl can have legal name of Charles. I have a grandfather like that, which made it difficult to find information.
