Unnamed Sister of Rosa Millard

Readers meet Granny's sister Louisa Hawk, who lives in Alabama, but both "Retreat" and The Unvanquished refer to another sister, who is neither named nor described but only mentioned: Granny explains the trip she's taking by saying that "My sister lives in Memphis, we are going there" (24, 56). Since "Millard" is Granny's married name, we have no way of knowing the name of her sister; however, she may be the mother of Cousin Melisandre who appears in "My Grandmother Millard and General Bedford Forrest and the Battle of Harrykin Creek."
