His death certificate records John McClurg, age 16 years 6 months 17 days, born 22 July 1919 in Morehead, Ky, died 8 Jan 1937 in Lexington, Fayette Co., Ky, single, father Luie McClurg, mother Laura McClurg maiden name not known, cause of death lacerations of the brain due to fractured skull, accident, fell at home, informant Mrs. N.L. Wells, Morehead, Ky, burial in Lee Cemetery.

His gravestone is inscribed John F. McClurg, July 22, 1920 - Jan 7, 1937.

Since he did not appear in the 1920 census (taken in January) the 1920 birthdate is probably the correct one. I cannot find him in the Kentucky birth records.
