Mabelle White Born IN Atlanta GA

She was Mabelle born Nov. 29, 1874 in Atlanta, GA. She married Harry Marshall Powell LEACH. They moved to Tennessee. I believe they were married in GA. Their children were Edward (Harry), Marion (Francis), Adelaide and Lewis (my grandfather). Both Mabelle and Harry died in Tennessee and are buried in Chattanooga Memorial Cemetery. I am looking for any information on Mabelle WHITE's ancestors.
