My grandfather Henry Elliott MATHIS, b 1877 in Randolph co. GA, had an older half-brother named Benjamin E. COX, b.1863. My grandmother's first name was Frances H., but I have not been able to find her maiden name nor Benjamin's father's first name. Do these names fit into the family tree of anyone out there. Maybe Ben's father was in the civil war. There were several COX's from Randolph co. but without a first name there is no way I'll ever know. I have looked for a marriage record using her first name and his last, but no luck.
