Hi there, Mary.
I'm not related and I don't live in the county. I answer query board posts the way normal people do cross-word puzzles.
I didn't find his obit. I did find out a little bit about him, including his exact death date. Maybe some gracious, kind-hearted soul will look his obit up in the local paper.
Here is what I found:
MASON, GEORGE RALPH
b. 01/06/1916 WEST VIRGINIA
d. CONTRA COSTA 07/17/1986
Name: George Mason
Last Residence: 94521Concord, Contra Costa, California

Name: George Ralph Mason
Birth Date: 1916
Birth Place: Berkeley, West Virginia
FHL Film Number: 831268

Mason, S Roy, head, 25, WV, WV, Penn
Mason, Edith, wife, 20, WV, Penn, WV
Mason, George, son, 4, WV, WV, WV
Smith, John, Servant, 20, Va, Va, Va
Kettering, Martha, Sister-in-law, 15, WV, Penn, WV
The fact that his sister-in-law, Martha, has the same last name, Kettering, as George's mother's maiden name in the California death record, above, is pretty strong evidence that Edith Mason, wife, is Edith Kettering, and the George who is just 4 in 1920 is your George.
He may have gotten into trouble.

Mason, George R, Inmate, Male White 14
He is at the WV Industrial School for Boys, which was a juvinile prison.
He may just have been dumped there by his dad, when Edith died.

Edith E Kettering 9
Martha M Kettering 5
Ida M Kettering 8/12
There is Martha, b. 1905, the same as the Martha who is sister-in-law in 1920. That and th efact th eparents' names match tells us this is Edith's family.
Lee Roy Mason registered for the draft in 1917. He was born
29 Sep 1894 in Berkeley County. In 1918 he had a wife and one son under 2 years, which would be George, so the WWI one is almost certainly our "S Roy"; "L" and "S" look awfully similar in cursive, so he may be "L Roy" in 1920 and the transcribers made a mistake.
has his death record
Name: Lee Roy Mason
Death Date: 20 Feb 1965
Death Place: Jefferson, West Virginia
Father's Name: George A. Mason
Mother's Name: Rebecca J. Felker
Birth date: 29 Sep 1894, same as the WWI Draft card
Lee Roy and Edith are both on Find-a-Grave
in Berkeley County.
I hope this helps.
