below text that follows ASL signing above:
SOME HEARING PEOPLE DON'T KNOW THEIR GENES A hearing woman was surprised to have two deaf daughters. She had no deaf members in her family or in her husband's family for about 2 or 3 generations. She was still puzzled about it, and decided to research her family tree. She went to libraries, archives and spoke with very distant members of the family tree. Her research went back to about ten generations. She then discovered she had several deaf members way back in the past. How many people want to do heavy family history research? Some do, but many don't.
