The Florida Death Index (at Ancestry.com) provides these dates:

James Dewey Chesser, b. Feb. 8, 1910, d Feb 16, 1974 in Okaloosa Co. Florida.

An uncited source states that James's birthdate was Feb 25, 1910 in Covington County, Alabama, and that he was the son of James Wright Chesser (b. 1881 Covington Co. Alabama) and Lena Davis. His death date is the same in this online source.

Hopefully, this information will be helpful for CHESSHER researchers (and surname variations such as CHESER, CHESSER, CHESHER) as they try to sort through all the possibilities and gives a starting point. Be sure to verify all sources and good luck!
