I tend to think there is some problem when cousins marry. On both my maternal and paternal sides cousins married several generations back and I know of several cases of bi-polar, ADHD, depression and alcoholism. I suspect there is some connection. Of course, it does make genealogy a little easier when you get back 6 or 7 generations and have the same set of parents down a couple of times. I enjoy all the conversation here, its great. Vernia
