I had never heard that before about the seventh son having healing powers. My great grandmother was born three months after her father was killed in the Civil War. They say that children born after the father dies have healing powers. She actually did have ability to heal as witnessed by my father. He said that people would come from all over to have her breathe on their babies to cure them of thrush. I remember him telling me that he would see someone walking up the road carrying a baby and he would "go get grandma". They would come aknockin on the door. She would lay the baby in her lap and breathe into the babies mouth. Apparently, it worked because she had quite a reputation. I don't know if she could do any other healing but she could recite the alphabet backwards. My family originated in Northern Ireland and came to the rural South through Virginia. They are MAXWELLS, BREEDINGS, WINTONS, LYLES, GARRISONS, GRANTLANDS. She was Mary Thomas Lyle Grantland. Judy
