My great grandpa was the 7th son/7th son. He was known for stop bleeding & heal the burns, and miner ailments like worms in children. He had some rules hat went with healing. The rule was, he could pass his powers to his blood relatives with more rule, a man could pass the power to a female blood relatives & she then passed it to a male blood relatives and so on, never pass to the same sex, I don't know what would happen if you did. He also would say a few words while circling the patient..this has been passed in my family and I wrote down the words he would say. I have never had to use it and don't know of any special powers. I do have dreams that came true, one was an airplane crash & my friend died, the next day it happened , creeped me out.
