The family bible authenticity validated by online birth certificates: Willie Edward Malone (10 May 1913) and Bradley Malone (24 Aug 1929). That info found https://familysearch.org/
Also found same website are death certificates: C. B. Malone (8 Feb 1867 - 25 Mar 1951) and Florence Allie Malone (14 Oct 1887 - 19 Mar 1947). Your grandfather wed 22 Sep 1895, C. B. wed Mittie Caroline Bodine 8 May 1900, and Louiza Jane Malone filed for Civil War Widow's Pension 9 Sep 1899. All of those events took place in Fannin County and that's strong evidence of kinship.
