Attempting to discover a 'link' through my grandmother

My grandmother's name was CORA LOUISE SEVIER.I've also seen her middle name as LOUISA so I don't know which is correct.Born in Tennessee, as a very young child she was left alone for a few minutes (I was told by a young black girl who slipped out to see her boyfriend) and fell into the fireplace permanently damaging one of her arms. It looked burned and had little strength.

She married Ignacio Cordova but I don't know the date nor state.She lived for many years in San Antonio, Texas and died there.She had several boys and one girl, my mother, Mary Louise Cordova who married Daniel B. Phipps. I was born in Texas and later we moved to my father's home state of Idaho.
