The Martha Hardee born Oct 3, 1852 and died March 11, 1948 buried in Bayboro Baptist Church was the wife of Isaiah Calvin Hardee. Her son is Julius B Hardee b Dec 1888 and died 1970 who is also buried in the cemetery. Isaiah was the brother of Purify Hardee and the uncle of William Henry Hardee.
The Martha Hardee that is buried in Riverside Cemetery was maiden name Gause and her sons were Robert Pearlie Hardee and Dewey Hardee according to her obituary but they are both not the person I am researching.
