This is Dan Miller, father of Lelia Swan Miller. Leila Swan Miller was the wife of James Karnes Polk Shumate, my 2nd Great Grandfather, making her my 2nd Great Grandmother. Thus, Dan Miller, above, is my 3rd Great Grandfather.
My mind is exploding, it still isn’t quite real, that I really have solved this mystery. But I did. Idid it. Idid it.
