Who was Archie?

Obviously Archie was her son, who died six months earlier at age 60. Maggie must have been in her 80s, poor dear, and her grief at outliving her son was poignant and fresh. In another letter later that August to "My Dear Gladys" she wrote, "I have had a long hot, and very sad summer. I miss my precious Archie more, not less, as time passes, tho I try hard to be reconciled. Just can't have enthusiasm for anything anymore."

But who was Archie to me? Who was Maggie to me? Gladys was Great Aunt Gladys, sister to Pop Thames. Daddy referred to her as Aunt Happy-Tail, much to the delight of us children and the irritation of Mamoo. The letters to Gladys were in an envelop addressed to John and Sylvia Thames from Mel Ingram, son of Aunt Gladys.

I searched the Rembert book for a Margaret Clark and found one. But this was a daughter of William Clark, the ancester who fought for the Confederacy, which would explain her "Real Daughters" activity. But she was writing in 1967. How could a daughter of the Confederacy still be alive in 1967? The Rembert book didn't carry forward to list the offspring so that I could confirm the Margaret Clark was Maggie by seeing a son named Archie.
