I've heard some really nasty stories about the people in my husband's family. They had 2 uncles that slept with their own nieces. They both got pregnant and had the babies, of course one of the babies was born mentally retarded. Then they had to first cousins that had a baby together. Disgusting! Maybe no one else besides their own family members would sleep with them, or their just plain demented. I don't know what is up with that family.
