Tabanus: Possibly John Carol Barnes, but I can't be sure.1953 Louisiana championship: <The youngest player here is 20-year-old John Barnes of New Orleans> (STA 5 Sep 1953). Edward Borsodi and Fred Cummimgs won with 5/6, and Barnes shared 8th place with 3.5/6 (STA 8 Sep 1953)
1954: "Alfred B. Wills, winner of the New Orleans City Chess Championship tournament, and <John Barnes, winner of the reserve tournament>, were presented trophies during a meeting of the New Orleans Chess Club Friday night at the Young Men's Christian Association." (Times-Picayune, 27 March 1954, page 18). With a photo of Wills, David A. Walsdorf Jr. (president of the club), and John Barnes in shirt and tie holding a pocal.

Reposted from User: crawfb5 in the Biographer Bistro :
I have the USCF newsletters from the 1950s on disc. The two Barnes games in the database are from the 1954 US Open in New Orleans. Barnes finshed 50-64th in a field of 109 players with a 6-6 score. This seemed like a good year to start a search.
He won the <Reserve> section of the 1953-4 New Orleans City Championship with a score of 10-1. He did not play in the 1954 Louisiana State Championship.
He was rated 1913 on the 1954 rating list. He was not on the 1959 list.
